  SAP Error Message: WSTP027
  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 can be protected by authorization objects to restrict access to sensitive or specific sets of materials.
  The authorization check typically involves the authorization object M_MATE_MAT (Material: Material Type and Material Group) or similar, which controls access based on material groups.
  
  Explanation
  
  The system checks the user's authorizations when they try to display or process materials.
  If the user tries to access materials from a material group for which they lack authorization, the system raises this error.
  The placeholder &1 in the message will be replaced by the actual material group code that the user tried to access.
  
  
  Solution
  
  
  Check User Authorizations:
  
  Use transaction SU53 immediately after the error occurs to see which authorization check failed.
  Alternatively, check the authorization trace using ST01 (Authorization Trace) for the user.
  
  
  
  Identify the Missing Authorization:
  
  The missing authorization is usually related to the authorization object M_MATE_MAT.
  This object contains fields like:
  
  MATKL (Material Group)
  MTART (Material Type)
  
  
  
  
  
  Update User Roles:
  
  Add the required material group(s) to the user's role(s) in transaction PFCG.
  Ensure that the user has the necessary authorization for the material group(s) they need to access.
  If the user should have access to all material groups, the authorization can be set to * (all).
  
  
  
  Transport and Test:
  
  After updating the roles, transport the changes if necessary.
  Have the user log off and log back in, then test the access again.
  
  
  
  
  Related Information
  
  
  Authorization Object: M_MATE_MAT
  
  Controls access to materials based on material type and material group.
  
  
  Transactions to check:
  
  SU53 – Display last authorization check failure.
  ST01 – Authorization trace.
  PFCG – Role maintenance.
  MM03 – Display material master (where the error might occur).
  
  
  
  Notes:
  
  Sometimes, the error can also occur if the material group is newly created and roles have not been updated accordingly.
  Ensure that the material group exists and is correctly maintained in the system.
