Features
This module provides the capability to add dynamically additional fields on a User Request in order to better qualify it. The additional fields proposed will be different based on the selected Service / Service Subcategory.
For instance when a user asks for a “new virtual machine”, then
we may want him to provide the number of CPUs, the quantity of RAM
and the type of OS in
structured fields rather than hoping that the user will provide
them by himself, in the Description
field.
You just have to define your template and then when a user creates a ticket, the additional fields will appear in the ticket edition form, based on the selected service subcategory.
A request template is related to a service subcategory. A request template can add one or multiple additional fields to User Requests. The additional fields can be of the following types:
-
Date and Date Time
-
String (formated with regular expression if needed)
-
Text area
-
CSV list
-
List based on OQL query
-
Duration
-
Readonly/hidden fields

Limitations
-
This extension is designed for UserRequest and Incident tickets only. See Q&A: on "Change" class for customizing it for another class.
on usage
-
When defining
Fields
give them different labels or only the first one will be displayed in read mode. -
Be cautious, when you define possible values in a Request Template Field, with an OQL query, this features has limitations
-
You cannot depend on (in the OQL query) an ExternalField declared on the Ticket (such as
team_name
), as the proposed values won't be refreshed upon a change of team. Classical external fields you may be tempted to use but should not:caller_name
,org_name
,agent_name
,team_name
,service_name
,servicesubcategory_name
. See Q&A: Values not refreshed for examples and workaround. -
You cannot use (in the OQL query) a Ticket field which is not displayed to the user on the Portal, as it crashes the Portal.
-
Access restriction: The OQL query will display all objects on the Portal, it ignores user scopes. The only security filtering applied are related to the User Profiles and Allowed Organizations, not the portal Scopes. Include those constraints in the OQL query if this is a requirement for you.
-
You cannot on that OQL query specify any “ignore_silo” constrains.
-
Show obsolete data
user preference is not taken into account. If you don't want obsolete objects to be proposed, put it in your query.
If user preference were taken into account, you would not be able to request through a service the reactivation of an obsolete object, selected in a Request Template field. In such case, some users could not fill the request because they would not see the obsolete objects, painful, no!. -
Conditional field comes with a limitation, if it is not displayed in the initial form, then its initial value is never displayed.fixed in 2.3.4
-
-
The type of data which can be displayed and requested within a request Template does not supports all fields,
-
You cannot prompt the user for Image, File, HTML, nor multi-valued fields like TagSet, EnumSet, Caselog,…
-
You cannot provide html information such as clickable URL, image, file,…
-
-
When creating a UserRequest, there is no way to prefill the fields of the
service_details
request template, as they are not known by the data model -
On notification the only supported placeholder is $this->service_details$ which displays the full content of the Request template. It is not possible to only reference a single field of a template.
on import & export
-
Because of its design, some “standard” itop capabilities are not available.
-
You cannot do a CSV export of UserRequest with one column per Request Template Fields. You will have to do it with Excel.
-
You cannot CSV import UserRequest with their filled Template (
service_details
field) -
You cannot fill through a REST API call, the template of a UserRequest (
service_details
field) -
You cannot in the UI, filter UserRequest based on values they have in the dynamic fields brought by request templates
-
The way to query UserRequest having one value in a particular request template field and another value in another request template field, is rather tricky due to iTop OQL limitation, see Q&A: Reporting for how to do it.
-
Installation & upgrade
Use the Standard installation process for this extension.
Upgrade: In order to be able to search for old User Requests which do have a particular value set in a request template, the iTop administrator need to run once a special page which explode every (User Request) template data into new tables, so it can be queried with OQL.
php populateTemplateFieldValue.php --append
You can either use “--append” or “--reset”, same results, might differ in execution time.
-
--reset recomputes from scratch
-
--append explode only the template data which have not been exploded yet
Configuration
The following settings can be adjusted in the iTop configuration
file, in the section itop-request-template
:
Parameter | Type | Description | Default Value |
---|---|---|---|
copy_to_log | string | The attribute into which the template values should be copied. Set to an empty string to disable this behavior. | public_log |
The following settings can be adjusted in the iTop configuration
file, in the section templates-base
:
Parameter | Type | Description | Default Value |
---|---|---|---|
hidden_fields_profiles | string | CSV list of profiles. If the user has ANY of the listed profile, she will NOT see the fields of type “hidden”. | Portal user |
reset_fields_on_template_change | boolean | If set to “true”, fields value will be reset when changing template, even if some of the fields have the same code. | false |
view_extra_data | string | relations |
Usage
Create request template
From the Service Management menu, click on “Request template”:
The pages show a list of already defined request templates. Click on the button “new” to create a new one:
A request template is identified by its name the related service and service sub category.
The label is used on the portal to select a template if several are defined for a given service sub category.
The tab “Fields” is used to define the fields of the template:
Click on “Create a new field” to define a new one:
Here is a complete description of the properties:
Property | Description | Example |
---|---|---|
Code | Unique identifier, that can be used in the queries defined in another field. This value must be made of alphanumeric characters and cannot start with a number | model |
Order | An integer that defines in which order the fields are displayed in the form | 3 |
Label | Label seen by the user who is prompted for entering a value. Must be unique within a Template | Device Model |
Mandatory | Wether or not the user must enter/select a value | yes |
Input type | … see a detailed description below | List |
Values (OQL or CSV) | Used for drop-down lists only to
define the list of allowed values for this element. This can be
either a comma separated list of values (e.g.
“high,medium,low ”). The OQL can have a parameter in
the form :template->code , where code is the code of
another field. It can also use placeholder like
:current_contact->org_id or
:this->org_id which refer to the customer of the
Ticket |
SELECT Model WHERE brand_id = :template->brand |
Initial value | Used to set an initial value for text or text area fields | xyz |
Format | Allows you to define a regular expression for validating text fields | ^[a-zA-Z]$ |
Condition | New in 2.2.0 Condition on another field to display current field | :template->fieldcode1!='' |
Auto-complete threshold | New in 2.3.1 Threshold of
possible values above which the input switch to auto-completion.
Applicable for List and Drop-down list only if Values
is an OQL. Must be an integer. It uses
max_combo_length from iTop configuration when left
empty |
500 |
The syntax of a condition must be exactly following:
-
:template->
-
a field code (Should be a field of type List or Dropdown with a number of values below
max_combo_length
- Otherwise set on the Field anAuto-complete threshold
above the number of returned values) -
an operator = or !=
-
a fixed value which can be '' for empty or any text string inside simple quote
No blank or anything like that, except within the quotes of your
value. Example: :template->fieldcode2='no
way'
You cannot define a condition on 2 values or a condition on
multiple fields.
-
:template->fieldcode2='no' will not work if possible values for fieldcode2 are yes, no.
-
:template->fieldcode2='No' will not work if possible values for fieldcode2 are yes,no.
Remove value surrounding blank in Values (OQL or
CSV)
, otherwise the real value contains the spaces
Do not enter space before and after the comma between values.
Defining a dependent field, on a master field which would be a
Text
, a Text area
, a Date
, a
Date time
or a Dropdown
list in
autocomplete mode, is not well handled by the UI, it's blinking,
user can loose their entry, the behavior isn't user friendly.
To limit to … | use this regex within Format |
an email | [a-zA-Z0-9._&'-]+@[a-zA-Z0-9.-]+\.[a-zA-Z0-9-]{2,} |
a phone number | ^\+?[0-9\ ]{8,20}$ |
a url | https?,ftp)\://([a-zA-Z0-9+!*(),;?&=\$_.-]+(\:[a-zA-Z0-9+!*(),;?&=\$_.-]+)?@)?([a-zA-Z0-9-.]{3,})(\:[0-9]{2,5})?(/([a-zA-Z0-9%+\$_-]\.?)+)*/?(\?[a-zA-Z+&\$_.-][a-zA-Z0-9;:[\]@&%=+/\$_.-]*)?(#[a-zA-Z_.-][a-zA-Z0-9+\$_.-]*)? |
The input type can have one of the following values:
Input type | Description |
---|---|
Date | A pure date, entered by the mean of a calendar, or directly typed in |
Date and time | Date and time, entered by the mean of a calendar, or directly typed in |
Drop-down list | A list as defined by the property Values |
Duration | A time lapse |
Hidden | A value that will not be seen by the end-user (customer portal), but it will be seen by an agent (console) in modification only. The value is set by the mean of the property Initial value. The profile list is defined by the parameter hidden_fields_profiles |
List | A value to select amongst a list of proposed values. These values are defined by the mean of the property Values … |
Read-only | A value defined in Initial value, and which cannot be modified by anybody |
Text | A single line of text, which format may be enforced by setting Format |
Text area | A text with several lines |
The tab “Preview” displays a preview of the template as it will be displayed in the console:
Behavior on the Customer Portal
If a end-user selects a service sub-category on the customer portal which is related to a request template, the specific fields for this template are displayed, grouped under the denomination Service details.
This additional information is copied into the Public log when the User Request is created:
It is also possible for a Support Agent to see or edit the information in the details of the User Request, from the console:
Template placeholders
In a notification template, or anywhere else where a template can be used, the following placeholders will be available.
Assuming that this is a UserRequest:
-
$this->service_details$: a plain text representation of the selected values. This is suitable for a plain text email. Though it seems possible to use it within an HTML document, by using a PRE tag, this is NOT recommended because HTML entities (like <) still need to be escaped.
-
$this->html(service_details)$: an HTML representation of the selected values.
Hidden fields are forcibly excluded from the placeholders.
When a template value corresponds to an object selected into iTop, the returned value will be the friendly name of the object.
REST/JSON API
Read
To get the request template data, just pick the
service_details
field in your query. You'll get in the
returned JSON the values with :
-
template_id
: id for the RequestTemplate object used -
values
:-
Need
: RequestTemplate label -
one key per field, including the one that were hidden to the user
-
Example of a returned value:
-
{
-
"objects": {
-
"UserRequest::5": {
-
"code": 0,
-
"message": "",
-
"class": "UserRequest",
-

-
}
-
}
-
}
-
}
-
},
-
"code": 0,
-
"message": "Found: 1"
-

Write
You'll need to set the corresponding structure to the field you want to set :
-
template_id
: id for the RequestTemplate object used -
values
:-
one key per field, including the one that were hidden to the user
-
Example of a value to send (json_data payload):

Questions & Answers
Usage
Q: Performance issues with master field for dependent
fields being a text, date or auto-complete list?
A: This is a known limitation which is related to iTop core.
As a workaround, it is recommended to only use as master
field a List
or Drop-down list
with a very limited set of values, so if can be
selected in a drop-down and never with auto-complete mode.
Do not use as master field, other input type than
the recommended ones, as every key stroke in the master field,
would generate a reload of the request form, which lead to:
blinking, lost of user data entries, performance issue and
incorrect display.
Definition: A master field is referenced by at least one other field, within its condition
Reporting
Question: Can I get the UserRequest which do not have a
associated Request Template
Answer: Yes & No.
Query like this will fails
SELECT UserRequest WHERE ISNULL(service_details) = 1
While such query will work, with the limitation that if you have added or removed Request Template to service subcategories after the creation of User Request using those service Subcategories, then the result will be wrong.
SELECT u,rt FROM UserRequest AS u JOIN ServiceSubcategory AS ss ON u.servicesubcategory_id=ss.id JOIN RequestTemplate AS rt ON rt.servicesubcategory_id=ss.id WHERE ISNULL(rt.name) = 1
Question: Can I search for UserRequest which do have a
particular value in a field of the associated Request
Template
Answer: Yes with a recent enough version (above 2.1.0)
- Searching for a value
-
SELECT UserRequest AS u JOIN TemplateFieldValue AS v ON v.obj_key=u.id WHERE v.template_name="Laptop ordering" AND field_code='size' AND field_value='wide'
You must specify the name (or id) of the Request Template, as
the field_code
may not be sufficient to identify
uniquely a particular template, the same code could be used on
multiple Templates.
You can even get the UserRequest which uses a particular Template having a field which is pointing to an iTop object, and the iTop object is verifying some condition:
-
In that case, the Template Field definition has a
Values (OQL or CSV)
set with an OQL SELECT Model, -
we want to set a condition on the remote object, so here get the UserRequest pointing to a Model used for
Server
class.
- Searching for a related object
-
SELECT u,m FROM UserRequest AS u JOIN TemplateFieldValueLnk AS v ON v.obj_key=u.id JOIN Model AS m ON v.field_target_key = m.id WHERE v.template_name="Desktop ordering details" AND field_code='model' AND field_target_class='Model' AND m.type='Server'
TemplateFieldValueLnk
is a subclass of
TemplateFieldValue
, you will need to query that
subclass only if you need to set condition on the remote object,
otherwise if you just need the value of the model, it is stored in
TemplateFieldValue
.
Question: Can I search for UserRequest which do have a
particular value in a Request Template field and another value in
another Request Template field?
Answer: Yes, also it's tricky and as above requires a recent enough
version of the extension (above 2.1.0) - Thanks to
Synairgis Inc
for reporting this limitation
Usecase: Retrieve the UserRequest which have a Request Template named “test” and all those particular values in their Request Template fields:
-
a field with code “profile” must have “1” as its value,
-
and a field with code “contract” having “a” as its value,
-
and a field with code “site” having “Bordeaux” as its value.
Here is the non-working query, followed by the workaround
- not working
-
SELECT UserRequest AS u JOIN TemplateFieldValue AS v1 ON v1.obj_key=u.id JOIN TemplateFieldValue AS v2 ON v2.obj_key=u.id JOIN TemplateFieldValue AS v3 ON v3.obj_key=u.id WHERE (v1.template_name="test" AND v1.field_code="profile" AND v1.field_value="1") AND (v2.template_name="test" AND v2.field_code="contract" AND v2.field_value="a") AND (v3.template_name="test" AND v3.field_code="site" AND v3.field_value="Bordeaux")
- Working
-
SELECT UserRequest AS u JOIN TemplateFieldValue AS v1 ON v1.obj_key=u.id WHERE (v1.template_name="test" AND v1.field_code="profile" AND v1.field_value="1") AND u.id IN( SELECT UserRequest AS u JOIN TemplateFieldValue AS v2 ON v2.obj_key=u.id WHERE (v2.template_name="test" AND v2.field_code="contract" AND v2.field_value="a") AND u.id IN ( SELECT UserRequest AS u JOIN TemplateFieldValue AS v3 ON v3.obj_key=u.id WHERE (v3.template_name="test" AND v3.field_code="site" AND v3.field_value="Bordeaux")))
Question: Can I get with API REST the request
template fields and values for a given UserRequest
(id=234)?
Answer: Yes you can, the OQL to use would look like this:
- Searching for all values of a request
-
SELECT TemplateFieldValue WHERE obj_class='UserRequest' AND obj_key = '234'
Note: this class is currently limited to Administrator only. But it can be worked around by creating your own REST service.
Question: Can I display in an Attribute overview, the
UserRequests referencing the current object?
Answer: Yes you can, the OQL to use in the Dashlet would be based
on this one, with additional criterion to filter further if
required:
- Search from a remote object
-
SELECT UserRequest AS u JOIN TemplateFieldValueLnk AS l ON l.obj_key = u.id WHERE obj_class='UserRequest' AND field_target_class = :this->finalclass AND field_target_key = :this->id
Question: I have installed version 2.1, but OQL queries
does not return old User Request.
Answer: With version 2.1.0 or above of this extension, if you want
to perform queries over User Requests made prior to the deployement
of this version, you have to launch once, a cli script which will
explode the data created before into the new queryable objects.
The command requires to be on iTop server using the
web
user:
cd /path/to/itop/ cd env-production/templates-base/ php populateTemplateFieldValue.php --append
This command explodes not-yet-exploded CustomAttribute data into new objects TemplateFieldValue and TemplateFieldValueLnk.
Note: An alternate mode is php
populateTemplateFieldValue.php –reset
which empty the new
tables and rebuild them from scratch. Just after the upgrade to
2.1, the 2 modes are pretty similar.
User Portals
Question: I want to install this extension on my own
portal, how can I do it?
Answer: It requires to write an iTop extension. Add the below XML
to the creation Form of the UserRequest in your own portal
- itop_design / module_designs / module_design@my-itop-portal / forms
-
<form id="ticket-create"> <twig> <div class="form_field" data-field-id="service_details"/>
Here I suppose that the id of the Ticket creation form is called “ticket-create” but any id is possible, the important piece is the data-field-id which must be exactly service_details.
Question: I have installed this extension on an iTop
without itop-portal
and service_details
cannot be edited. Why?
Answer: That's an historical trick related to the old itop portal
prior to version 2.3.0. Here is what the extension does:
- itop_design / classes / class@UserRequest / lifecycle
-
<states> <state id="new"> <flags> <!-- If the modern portal is NOT installed, the custom fields will remain Read-Only --> <!-- Otherwise, the module itop-request-template-portal will enable the field in RW mode --> <attribute id="service_details" _delta="define"> <read_only/> </attribute> </flags> </state> </states>
to fix this you must alter the datamodel of the extension (so after it) in another extension.
- itop_design / classes / class@UserRequest / lifecycle
-
<states> <state id="new"> <flags> <attribute id="service_details" _delta="delete"/> </flags> </state> </states>
On "Change" class?
Question: I want to define RequestTemplate on the
“Change” class. Can I do it?
Answer: Yes, but it requires to write an iTop extension.
We assume that you have installed your iTop with “Change
Simple”. It's possible to do it even on full ITIL, but a bit
more complex
What is required:
-
Add fields
service_id
andservicesubcategory_id
to the class Change -
Add field
service_details
to the class Change -
Adapt presentation of the class Change to display the 3 above fields
-
Change ServiceSubcategory
request_type
field to include “change” as a valid value -
Customize the RequestTemplate method GetTargetClass() to return “Change” when appropriate
-
Change
servicesubcategory_id
filter on class UserRequest to not proposechange
related Service Subcategories
1) You will have to associate your Change to a Service and a
Service Subcategory, as it is the ServiceSubcategory which is the
link to retrieve the possible RequestTemplates applicable to an
object. It is possible to do without this assumption but it's
way more complex and won't be explained at all.
Check here if you
don't know how to add those fields service_id
and
servicesubcategory_id
to the class Change
- itop_design / classes / class@Change / fields
-
<field id="servicesubcategory_id" xsi:type="AttributeExternalKey" _delta="define"> <sql>servicesubcategory_id</sql> <is_null_allowed>true</is_null_allowed> <on_target_delete>DEL_MANUAL</on_target_delete> <target_class>ServiceSubcategory</target_class> <filter>SELECT ServiceSubcategory WHERE request_type='change'</filter> </field>
2) you will have to add this very particular field.
- itop_design / classes / class@Change / fields
-
<field id="service_details" xsi:type="AttributeCustomFields" _delta="define"> <handler_class>RequestTemplateFieldsHandler</handler_class> </field>
3) Of course, you need to redefine the presentation to add those 3 fields to the display of a Change object in the Console
- itop_design / classes / class@Change
-
<presentation> <details> ...
If you also have added the Change object to a portal refer to the above question for adding the request template as well on your Change in your Portal.
4) Add a change
value to the Service Subcategory
class, so you can flag in your Service catalog, the Subcategory
which are applicable to Change:
- itop_design / classes / class@ServiceSubcategory / fields
-
<field id="request_type" _delta="if_exists"> <values> <value id="change" _delta="define">change</value> </values> </field>
5) Redefine the RequestTemplate::GetTargetClass() method by the one below or something similar
- class:RequestTemplate
-
public function GetTargetClass() { $iSubCategory = $this->Get('servicesubcategory_id'); $oSubCategory = MetaModel::GetObject('ServiceSubcategory', $iSubCategory); if (is_null($oSubCategory)) { throw new Exception('Missing Service Subcategory'); } $sRequestType =$oSubCategory->Get('request_type'); if (($sRequestType == 'change') && (class_exists('Change'))) { return 'Change'; } if (($sRequestType == 'incident') && (class_exists('Incident'))) { return 'Incident'; } if (class_exists('UserRequest')) { return 'UserRequest'; } throw new Exception("The selected Service Subcategory is incompatible with your installation options (request type '$sRequestType' not supported)"); }
6) Portal adaptation
You may adapt this method to enable a Change creation on iTop
Portal upon selection of a ServiceSubcategory related to a
Change.
That's not enough, as you will need to add scopes
,
forms
and maybe brick
to manage correctly
the Change in the Portal, but this is another topic.
- class:Ticket
-
static public function CreateFromServiceSubcategory($oServiceSubcategory) { $sType = $oServiceSubcategory->Get('request_type'); if ($sType == 'change') { if (!class_exists('Change')) { throw new Exception('Could not create a ticket after the service ' .$oServiceSubcategory->Get('friendlyname').' of type '.$sType .': unknown class "Change"'); } $oRet = new Change(); } elseif ($sType == 'incident') { if (!class_exists('Incident')) { throw new Exception('Could not create a ticket after the service ' .$oServiceSubcategory->Get('friendlyname').' of type '.$sType .': unknown class "Incident"'); } $oRet = new Incident(); } else { if (!class_exists('UserRequest')) { throw new Exception('Could not create a ticket after the service ' .$oServiceSubcategory->Get('friendlyname').' of type '.$sType .': unknown class "UserRequest"'); } $oRet = new UserRequest(); } return $oRet; }
Request Template per Service?
Question: I want to define RequestTemplate on the
“Service” instead of the Service Subcategory. Can I do
it?
Answer: Yes, but it requires to write an iTop extension.
Here we propose to define RequestTemplate per Service, but you could imagine to do it per Organization, Priority or any combination of UserRequest fields
1) Customize RequestTemplate, to remove the field
servicesubcategory_id
and create a
service_id
ExternalKey field
- itop-design / classes / class@RequestTemplate / fields
-
<field id="servicesubcategory_id" _delta="delete"/> <field id="service_id" xsi:type="AttributeExternalKey" _delta="define"> <filter><![CDATA[SELECT Service AS s WHERE s.status != 'obsolete']]></filter> <dependencies/> <sql>service_id</sql> <target_class>Service</target_class> <is_null_allowed>false</is_null_allowed> <on_target_delete>DEL_AUTO</on_target_delete> <allow_target_creation>false</allow_target_creation> </field>
Modify the presentation as well… to reflect this change of field
2) Create a new TemplateFieldsHandler sub-class to change the way the applicable RequestTemplate are retrieved
class MyTemplateFieldsHandler extends TemplateFieldsHandler { /** * @return DBObjectSet of Templates */ protected function FindTemplates(DBObject $oHostObject) { $oSearch = DBSearch::FromOQL('SELECT RequestTemplate WHERE service_id= :criteria'); $oSet = new DBObjectSet($oSearch, array(), array('criteria' => $oHostObject->Get('service_id'))); return $oSet; } }
3) Change UserRequest service_details
field to use
the new TemplateFieldsHandler sub-class
- itop-design / classes / class@UserRequest / fields
-
<field id="service_details" xsi:type="AttributeCustomFields" _delta="must_exist"> <handler_class _delta="redefine">MyTemplateFieldsHandler</handler_class> </field>
Values not refreshed
Question: When I define possible values which depends on
xxx_name
which is a Ticket field, it does not
refresh.
Answer: Yes, this is a known limitation. team_name
is
an ExternalField, it's not a user provided field, it is computed
based on another user provided one, here team_id
.
Because of an iTop limitation (still present in 3.0)
dependencies on such type of field does not work. The list is not
refreshed, when that field is modified. There is a workaround, also
it makes the query writing a bit more complex sometimes.
First usecase: let's assume that you want to
display the servers linked to the Ticket Team
Here is the non-working version followed by the
workaround
- Non working version
-
SELECT Server AS s JOIN lnkContactToFunctionalCI AS l ON l.functionalci_id=s.id WHERE l.contact_name=:this->team_name
- Working version
-
SELECT Server AS s JOIN lnkContactToFunctionalCI AS l ON l.functionalci_id=s.id WHERE l.contact_id=:this->team_id
Second usecase: let's assume that you want to
display the servers belonging to the organization of the Ticket
Team
and that you have created a new ExternalField on UserRequest called
teamorg_id
computed as the organization id of the
team
- itop-design / classes / class@UserRequest / fields
-
<field id="teamorg_id" xsi:type="AttributeExternalField" _delta="define"> <extkey_attcode>team_id</extkey_attcode> <target_attcode>org_id</target_attcode> </field>
Here are the non-working version followed by the workaround
- Non working version
-
SELECT Server AS s WHERE s.org_id=:this->teamorg_id
- Working version
-
SELECT Server AS s JOIN Organization AS o ON s.org_id=o.id JOIN Contact AS c ON c.org_id=o.id WHERE c.id=:this->team_id
Wrong History
Question: When “service_details” is editable, every
ticket edition stores a modification of that field also it was not
modified
Answer: This is a known issue, which should be fixed one day, for
now, you can stop all history tracking on that field if you
wish:
- itop-design / classes / class@UserRequest / fields
-
<field id="service_details" xsi:type="AttributeCustomFields" _delta="must_exist"> <tracking_level _delta="force">none</tracking_level> </field>
