• What is the cause and solution for SAP error message /SAPAPO/SDP198 - Selection is locked - you are in display mode now ?

  The SAP error message /SAPAPO/SDP198 Selection is locked - you are in display mode now typically occurs in the context of SAP Advanced Planning and Optimization (APO) when a user attempts to modify or interact with a selection that is currently locked for editing. This can happen for various reasons, such as another user having the selection open for editing or a system process that has locked the selection.
  Cause:
  
  Concurrent Access: Another user is currently editing the same selection, which locks it for other users.
  System Lock: The system may have a lock on the selection due to a background job or process that is currently running.
  Display Mode: The user is in a mode that only allows viewing the data, not editing it.
  
  Solution:
  
  Check for Other Users: Verify if another user is currently editing the selection. If so, you may need to wait until they finish.
  Refresh the Session: Sometimes, simply refreshing the session or logging out and back in can resolve temporary locks.
  Use Transaction Codes: If you have the necessary authorizations, you can use transaction codes like SM12 to check for and manage locks in the system.
  Contact Administrator: If the issue persists, it may be necessary to contact your SAP system administrator to investigate further. They can check for any background jobs or processes that might be causing the lock.
  Change Mode: If you are in display mode and need to edit, ensure you switch to the appropriate mode that allows editing.
