  Causes:
  
  User Not Created in Backend: The user has not been created in the backend system (e.g., SAP ERP).

  Incorrect User Mapping: There may be a mismatch in user IDs or profiles between the front-end and back-end systems.

  Ensure that the user is created in the backend system. You can do this by using transaction code SU01 in the backend system to create the user.
