Before you can enable service field for requests, you need to create a request type for the requests.
To create a request type with service enabled, you need to enable the newly introduced Service field group for its Request Header Type.
You can define a new request header type or modify an existing Request Header Type to meet your business needs.
To define a new request header type:
On the PPM Workbench shortcut bar, select Demand Mgmt > Request Header Types.
The Request Header Type Workbench opens.
Click New Request Header Type.
The Request Header Type window opens.
Type a name in the Request Header Type Name field, for example, RHT_service.
The Reference Code field is populated automatically with the value you just provided for Request Header Type Name field.
Click Field Groups.
The Field Groups window opens.
Select field group Service: Allows selection to identify the service associated with the request.
The Service field group is added. It contains only one field: Service.
Double-click the newly added Service field.
The Field window opens.
Note: If you need to switch to Service List CMDB validation, We strongly recommend that you modify the server configuration parameter value to keep server configuration consistency. For more information, see the Solution Integrations Guide.
Changing validation value here in the Field workbench window is not recommended, as the change applies to the current request header type only.
Review the default settings provided. Make sure that you change default settings only when necessary. Click OK.
The new request header type is created.
