• What is the cause and solution for SAP error message ML020 - You have no authorization to display change documents ?

  The SAP error message ML020, which states "You have no authorization to display change documents," typically occurs when a user attempts to access change documents in the Material Management (MM) module but lacks the necessary authorizations.
  Cause:
  The error is primarily caused by insufficient authorization in the user's role or profile. In SAP, access to various functionalities, including viewing change documents, is controlled by authorization objects. If the user does not have the required permissions associated with these objects, they will encounter this error.
  Solution:
  To resolve the ML020 error, follow these steps:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after encountering the error. This will show you the last authorization check and help identify which specific authorization object is missing.
  
  
  
  Review Authorization Roles:
  
  Work with your SAP security team or administrator to review the roles assigned to your user account. Ensure that the roles include the necessary authorizations for displaying change documents.
  
  
  
  Authorization Objects:
  
  The relevant authorization objects for displaying change documents in the MM module may include:
  
  M_MATE_MAR: Material Master: Authorization for Material Master
  M_MATE_MAT: Material Master: Authorization for Material
  M_MATE_MA: Material Master: Authorization for Change Documents
  
  
  Ensure that the user has the necessary authorizations for these objects.
  
  
  
  Adjust Roles:
  
  If the required authorizations are missing, the security team can adjust the roles or create a new role that includes the necessary permissions.
  
  
  
  Testing:
  
  After adjustments are made, have the user log out and log back in to test if the issue is resolved.
  
  
  
  Documentation:
  
  Document any changes made to user roles or authorizations for future reference and compliance.
