• What is the cause and solution for SAP error message CPWB814 - Material master record is displayed in new session ?

  The SAP error message CPWB814 indicates that a material master record is being displayed in a new session. This typically occurs when a user attempts to access or edit a material master record that is already open in another session. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Multiple Sessions: The user has opened the material master record in more than one session. SAP restricts editing of the same record in multiple sessions to prevent data inconsistencies.
  Locking Mechanism: SAP uses a locking mechanism to ensure that only one user can edit a record at a time. If the record is already being edited or viewed in another session, it will prompt this error.
  User Configuration: Sometimes, user settings or configurations may lead to this error if the system is not properly handling session management.
  
  Solution:
  
  Close Other Sessions: Check if the material master record is open in another session. If so, close that session or navigate back to it to continue your work.
  Use Transaction Codes: If you need to view the material master record, you can use transaction codes like MM03 (Display Material) instead of trying to edit it in a new session.
  Log Off and Log Back In: If you are unable to find the other session, logging off and then logging back into the system can sometimes clear the session locks.
  Check for Background Jobs: Sometimes, background jobs or processes may hold locks on records. Check if there are any background jobs that might be affecting the material master record.
  Contact SAP Support: If the issue persists and you cannot identify the cause, it may be necessary to contact your SAP support team or consult SAP Notes for further assistance.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes for material management, such as MM01 (Create Material), MM02 (Change Material), and MM03 (Display Material).
