• What is the cause and solution for SAP error message PK340 - Not authorized to display supply areas ?

  The SAP error message PK340 ("Not authorized to display supply areas") typically occurs when a user attempts to access supply area information in the SAP system but lacks the necessary authorizations. This can happen in various modules, particularly in logistics and supply chain management.
  Cause:
  The primary cause of this error is a lack of authorization in the user's role or profile. The system checks the user's permissions against the authorization objects related to supply area access, and if the user does not have the required permissions, the error is triggered.
  Solution:
  To resolve the PK340 error, follow these steps:
  
  
  Check User Authorizations:
  
  Verify the user's roles and authorizations in the SAP system. This can be done by using transaction code SU53 immediately after the error occurs. This transaction will show the last authorization check and can help identify which specific authorization is missing.
  
  
  
  Review Authorization Objects:
  
  The relevant authorization objects for supply area access may include:
  
  M_MATE_WRK (Material Master: Plant Data)
  M_MATE_MA (Material Master: General Data)
  M_MATE_BW (Material Master: Basic Data)
  
  
  Ensure that the user has the necessary authorizations for these objects.
  
  
  
  Modify User Roles:
  
  If the user lacks the necessary authorizations, a security administrator or someone with the appropriate permissions should modify the user's roles to include the required authorizations. This may involve adding the user to a role that has the necessary access or creating a custom role.
  
  
  
  Testing:
  
  After making changes to the user's authorizations, have the user log out and log back in to the SAP system. Then, attempt to access the supply areas again to confirm that the issue has been resolved.
  
  
  
  Documentation:
  
  Document any changes made to user roles and authorizations for future reference and compliance purposes.
  
  
  
  Related Information:

  PFCG: Role Maintenance
  SU53: Authorization Check Analysis
  
  
  SAP Notes and Documentation:
  
  Check SAP Notes for any specific guidance or updates related to authorization issues.
  
  
  Security Best Practices:
  
  Regularly review user roles and authorizations to ensure they align with current job functions and security policies.
  
  
  
  If the issue persists after following these steps, it may be necessary to consult with your SAP Basis or security team for further investigation.
