  Error Message
  WX321 - No authorization for changing plant &
  
  Cause
  This error occurs when a user attempts to change the plant in a transaction or master data record but does not have the necessary authorization to do so. In SAP, authorizations are controlled via authorization objects, and changing certain fields like the plant requires specific permissions.
  Specifically, the user lacks the required authorization for the Plant field in the relevant authorization object(s), commonly:
  
  M_MATE_WRK (Material Master: Plant)
  M_MATE_WRK controls authorizations for material master data at the plant level.
  Other related authorization objects might be involved depending on the transaction, such as:
  
  M_BEST_BSA (Purchasing Document: Document Type)
  M_LIFNR_BSA (Vendor Master: Purchasing Organization)
  S_TCODE (Transaction Code authorization)
  
  
  
  
  When Does It Occur?
  
  When changing or creating material master data and trying to assign/change the plant.
  When changing purchasing info records or other plant-specific data.
  When performing transactions that involve plant-specific data changes without proper authorization.
  
  
  Solution
  
  
  Check User Authorizations:
  
  Use transaction SU53 immediately after the error occurs to check which authorization check failed.
  Alternatively, use ST01 (Authorization Trace) to trace the authorization check.
  
  
  
  Identify Missing Authorization:
  
  Look for missing authorizations related to the plant field, typically M_MATE_WRK.
  The authorization object M_MATE_WRK requires the following fields:
  
  Activity (ACTVT): Usually 02 (Change) or 03 (Display)
  Plant (WERKS): The plant(s) the user is authorized to change.
  
  
  
  
  
  Update User Roles:
  
  Add or update the user's role(s) to include the necessary authorization for the plant.
  In the role maintenance (transaction PFCG), add or adjust the authorization object M_MATE_WRK with the appropriate plant values and activities.
  Ensure the user has the correct activity (e.g., 02 for change).
  
  
  
  Transport Changes:
  
  If roles are changed in a development system, transport the changes to quality and production systems as per your change management process.
  
  
  
  Test:
  
  After updating authorizations, test the transaction again to confirm the error is resolved.
  
  
  
  
  Additional Information
  
  
  Authorization Object M_MATE_WRK:
  
  Controls access to material master data at the plant level.
  Fields:
  
  Activity (ACTVT): 01 (Create), 02 (Change), 03 (Display), etc.
  Plant (WERKS): Plant(s) for which the user has authorization.
  
  
  
  
  
  Best Practices:
  
  Avoid giving broad authorizations (e.g., all plants) unless necessary.
  Use authorization groups if applicable to restrict access further.
  Regularly review user roles and authorizations to maintain security compliance.
