When we instantiated the application in SAP BTP, Role Collections were automatically created.

Now, we need to map the Role Collections to the User Groups we created in the IdP (IAS).
Steps
From the previous screen, select the role by clicking into each of them to create the mappings. You need to enter the name attribute of the user group in the Name field.
When it is saved, the screen will show the mapping of the name attribute to the Identity Provider.
In the role collections main screen, it is possible to see the mapping to the user groups.
Video Summary
This educational video showcases the process of mapping role collections from a SAP BTP subaccount to user groups within an EIS IDP. Set within the context of a 'SAP Intelligent Agriculture Instance' on a subaccount, it is noted that role collections are automatically generated during the instance setup.
Critical to the process is aligning these role collections with the relevant user groups in the IDP. The video demonstrates this by mapping each role collection to each user group, with particular focus on the use of the 'name attribute'. Upon completion, a review confirms the successful implementation of the mapping process, providing viewers with a clear understanding of role mapping in a SAP BTP subaccount.
