The SAP error message GK078 indicates that a user does not have the necessary authorization to perform a subassignment for a specific characteristic value in the context of Profitability Analysis (CO-PA) or similar modules. This error typically arises when a user attempts to access or manipulate data that they are not authorized to handle.
Cause: Missing Authorizations: The user lacks the required authorization for the specific characteristic or value they are trying to access. Authorization Object: The relevant authorization object (e.g., S_COPA) may not be properly configured for the user role. Characteristic Value Restrictions: The characteristic value being accessed may have restrictions that prevent certain users from making changes or viewing it.
Solution: Check User Roles: Verify the roles assigned to the user in transaction SU01 (User Maintenance). Ensure that the user has the necessary roles that include the required authorizations. Review Authorization Objects: Use transaction SU53 immediately after the error occurs to check the authorization check
