  SAP Error Message: WSTP028
  Message Text:
  
  You are not authorized to display materials from material group &1
  
  Cause
  This error occurs because the user does not have the necessary authorization to display or access materials belonging to a specific material group. In SAP, material groups are often protected by authorization objects to restrict access to sensitive or specific sets of materials.
  The authorization check typically involves the authorization object M_MATE_MAR (Material Master: Authorization for Material Groups) or similar, which controls access based on material groups.
  
  Solution
  
  
  Check User Authorizations:
  
  Verify the user's roles and authorizations in transaction SU01 or PFCG.
  Specifically, check if the user has the authorization for the material group mentioned in the error message.
  
  
  
  Adjust Authorizations:
  
  If the user needs access, update their roles to include the required material group(s).
  Add or modify the authorization object M_MATE_MAR with the appropriate material group values.
  Example: Add the material group(s) to the field MATKL in the authorization object.
  
  
  
  Testing:
  
  After updating the roles, have the user log off and log back in.
  Test the material display transaction again (e.g., MM03).
  
  
  
  If Access Should Be Restricted:
  
  If the user should not have access, no action is needed.
  Inform the user about the restriction.
