  The SAP error message BUPA_MASS018 typically occurs during mass changes to business partner data in the SAP system. This error indicates that there is a key change being attempted for a business partner, but the system has detected that the change would affect multiple entries (or lines) in the database, which is not allowed in certain contexts.
  Cause:
  The error message BUPA_MASS018 is triggered when:
  
  You are trying to change a key field (like the business partner number) for multiple entries at once.

  Use the Correct Transaction: Make sure you are using the appropriate transaction code for mass changes. For business partners, you might use transactions like BP or BP_MASS_CHANGE.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on mass changes to business partners. There may be restrictions or best practices outlined.
