• What is the cause and solution for SAP error message /PM0/ABP_ADM_FE018 - Sample &1 is locked ?

  The SAP error message /PM0/ABP_ADM_FE018 Sample &1 is locked typically indicates that a specific sample (identified by &1) is currently locked in the system, preventing any modifications or access to it. This locking mechanism is often in place to ensure data integrity and prevent concurrent updates that could lead to inconsistencies.
  Causes:
  
  Concurrent Access: Another user or process is currently accessing or modifying the sample, leading to a lock.
  Incomplete Transactions: A previous transaction involving the sample may not have been completed, leaving it in a locked state.
  System Errors: Technical issues or system errors may have caused the sample to remain locked.
  Long-running Processes: Background jobs or long-running processes that involve the sample may be holding the lock.
  
  Solutions:
  
  Wait and Retry: If the lock is due to another user or process, waiting for a short period and then retrying the operation may resolve the issue.
  Check Lock Entries: Use transaction code SM12 to check for lock entries. You can search for the specific sample number to see if it is locked and by whom.
  Release Locks: If you have the necessary authorizations, you can manually release the lock from SM12. Be cautious when doing this, as it may lead to data inconsistencies if the other process is still active.
  Identify the Locking Process: If a specific user or process is locking the sample, communicate with them to understand why the lock is in place and if it can be released.
  Review Background Jobs: Check if there are any background jobs that might be holding the lock. You can use transaction SM37 to monitor background jobs.
  System Restart: In rare cases, a system restart may be necessary to clear any persistent locks caused by system errors.
  
  Related Information:
