• What is the cause and solution for SAP error message W5028 - You have no authorization to display this reservation ?

  SAP Error Message:
  
  W5028 - You have no authorization to display this reservation
  
  Cause:
  This error occurs because the user trying to display a reservation in SAP does not have the necessary authorization to view that reservation. In SAP, authorizations control access to various transactions and data objects. If the user’s role or profile lacks the required authorization objects or values, the system will prevent access and show this message.
  
  Explanation:
  
  Reservation in SAP typically refers to a material reservation (e.g., in Materials Management - MM).
  Displaying or processing reservations requires specific authorizations.
  The authorization check usually involves objects like M_MATE_WRK (Material Master: Plant Data) or M_RESV_BES (Reservation: Authorization for Processing).
  If the user’s authorization profile does not include the required permissions for the plant, movement type, or reservation type, the system denies access.
  
  
  Solution:
  
  
  Check User Authorizations:
  
  Use transaction SU53 immediately after the error occurs to see which authorization check failed.
  This transaction shows the last failed authorization check for the user.
  
  
  
  Identify Missing Authorization Objects:
  
  Common authorization objects related to reservations include:
  
  M_RESV_BES (Reservation: Authorization for Processing)
  M_MATE_WRK (Material Master: Plant Data)
  M_MATE_MAR (Material Master: General Data)
  
  
  Check if the user has the required values for these objects, especially for the plant and movement type involved.
  
  
  
  Adjust User Roles/Profiles:
  
  Update the user’s role in PFCG to include the necessary authorizations.
  Add or extend the authorization objects with the correct values (e.g., plant, movement type).
  Transport the updated role to the production system if needed.
  
  
  
  Test Access:
  
  After updating authorizations, have the user try to display the reservation again.
  Use SU53 again if the problem persists.
  
  
  
  Consult Basis or Security Team:
  
  If you do not have authorization to change roles, coordinate with your SAP security team.

  Transaction Codes:
  
  MB22 - Change Reservation
  MB23 - Display Reservation
  SU53 - Display Authorization Check
  PFCG - Role Maintenance
  
  
  
  Authorization Objects:
  
  M_RESV_BES - Reservation: Authorization for Processing
  M_MATE_WRK - Material Master: Plant Data
  M_MATE_MAR - Material Master: General Data
  
  
  
  Notes:
  
  Always ensure that authorizations follow the principle of least privilege.
  Avoid giving broad authorizations unless necessary.
  Check if the reservation belongs to a plant or organizational unit outside the user’s authorization scope.
  
  
  
  
  Summary:
  Error W5028 means the user lacks the authorization to display the reservation. The fix involves checking the failed authorization with SU53, identifying missing authorization objects (commonly M_RESV_BES), and updating the user’s roles accordingly to grant the necessary permissions for the relevant plant and reservation type.
