• What is the cause and solution for SAP error message MI546 - No maintenance authorization for class &; only display possible ?

  The SAP error message MI546 ("No maintenance authorization for class &; only display possible") typically occurs when a user attempts to perform maintenance activities on a classification system (such as creating, changing, or deleting a classification) but lacks the necessary authorizations to do so. This error is related to the authorization checks in SAP, specifically for the classification system.
  Cause:
  
  Lack of Authorization: The user does not have the required authorization to perform maintenance on the specified class.
  Authorization Object: The relevant authorization object (e.g., C_TCLAS for class management) is not assigned to the user’s role.
  Display-Only Role: The user may have a role that only allows display access, preventing any changes to the classification.
  
  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 maintenance authorizations for the classification system.
  
  
  Review Authorization Objects: Check the authorization objects related to classification management. The key authorization object is C_TCLAS, which controls access to class maintenance. Ensure that the user has the necessary authorizations for this object.
  
  
  Modify Roles: If the user lacks the necessary authorizations, you may need to modify their 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, consult with your SAP security team or administrator to request the required access.
  
  
  Testing: After making changes to the user’s roles or authorizations, have the user log out and log back in to ensure that the changes take effect. Then, test the functionality again to see if the error persists.
