• What is the cause and solution for SAP error message CPWB813 - Change master record is displayed in new session ?

  The SAP error message CPWB813, which states "Change master record is displayed in new session," typically occurs when you attempt to change a master record (such as a material master, vendor master, etc.) while another session is already open for that same record. This is a common issue in SAP when multiple users or sessions are trying to access or modify the same data simultaneously.
  
  Cause:
  
  Concurrent Access: The primary cause of this error is that the master record you are trying to change is already being accessed in another session. SAP locks the record to prevent data inconsistencies.

  Solution:
  
  Close Other Sessions: Check if you have another session open that is currently displaying or editing the same master record. If so, close that session or navigate away
