3495075 - Unable to create restrictions for Purchase Order Document Types

SAP S/4HANA Cloud Public Edition

System standard design

The behavior described is expected when a user has two business roles assigned that contain the same business catalogs and/or restriction types. If one of the business roles is unrestricted, the user gets unrestricted access even if the user assigned to a business role with restricted access.

From release 2508, the IAM transactions can be used to restrict the access See more information  Work with IAM Apps of the App Authorization Variant Type | SAP Help Portal
