  The SAP error message /PM0/AB_IBC_CNFG_I_C321 Application &1 is locked typically indicates that a specific application or configuration within the SAP system is currently locked, preventing further changes or access. This can occur for various reasons, such as ongoing maintenance, a previous session that did not close properly, or a user having an active lock on the application.
  Causes:
  
  Active Locks: Another user or process may have locked the application for editing or configuration.
  Incomplete Transactions: A previous transaction may not have been completed, leaving the application in a locked state.
  System Maintenance: The application may be locked due to scheduled maintenance or updates being applied.
  Authorization Issues: The user may not have the necessary permissions to access or modify the application, leading to a perceived lock.
  
  Solutions:
  
  
  Check Lock Entries:
  
  Use transaction code SM12 to view and manage lock entries. You can check if there are any active locks on the application and who holds them.
  If you find a lock that is no longer needed, you can delete it (if you have the necessary authorizations).
  
  
  
  Contact the User:
  
  If another user is holding the lock, communicate with them to see if they can release it or if they are done with their task.
  
  
  
  Review Transaction Logs:
  
  Check transaction logs or system messages to identify if there was an error or issue that caused the lock.
  
  
  
  Wait and Retry:
  
  If the lock is due to a scheduled maintenance or a temporary process, waiting for a while and then retrying may resolve the issue.
  
  
  
  Check Authorizations:
  
  Ensure that your user account has the necessary authorizations to access and modify the application. If not, contact your SAP administrator to adjust your permissions.
  
  
  
  System Restart:
  
  In some cases, a system restart may be necessary to clear locks, especially if they are due to a system error.
