Hi @CBEN2024
For this case, you can create new Aggregate group method. In this method you must set a valid url context (for example context url to test connection).
In Response attribute mapping section, you can set a attribute name of your group schema, and static value in the attribute pacth value. For example you can create a attribute in your group schema called EntName, and in the attribute path, you can set the value ./“EntitlementTest”
Then, If you execute aggregate group task, EntitlementTest entitlement will be created
