• What is the cause and solution for SAP error message MI547 - No authorization for class &; end of transaction ?

  The SAP error message MI547 ("No authorization for class &; end of transaction") typically occurs when a user attempts to perform an action related to a specific class (such as a material class or a document class) but does not have the necessary authorizations to do so. This can happen in various transactions, particularly in inventory management or material management processes.
  Cause:
  
  Missing Authorization: The user does not have the required authorization for the specific class of objects they are trying to access or manipulate.
  Authorization Object: The authorization check is failing due to missing entries in the relevant authorization objects (e.g., M_MATE_WRK, M_MATE_DATA, etc.).
  Role Assignment: The user’s role may not include the necessary permissions for the class in question.
  
  Solution:
  
  
  Check User Roles: Verify the roles assigned to the user in transaction SU01 (User Maintenance). Ensure that the user has the appropriate roles that include the necessary authorizations for the class.
  
  
  Review Authorization Objects: Use transaction SU53 immediately after the error occurs to check which authorization object is causing the issue. This transaction shows the last authorization check and can help identify what is missing.
  
  
  Modify Roles: If the necessary authorizations are missing, you may need to modify the user’s roles or create a new role that includes the required authorizations. This can be done in transaction PFCG (Role Maintenance).
  
  
  Consult with Security Team: If you do not have the necessary permissions to change roles or authorizations, contact your SAP security team or administrator to request the required access.
  
  
  Testing: After making changes, have the user log out and log back in to ensure that the new authorizations take effect. Test the transaction again to confirm that the issue is resolved.
