• What is the cause and solution for SAP error message WS_CWB011 - Complaint &1 cannot be locked ?

  The SAP error message:
  WS_CWB011 Complaint &1 cannot be locked
  Meaning / Cause:
  This error occurs when the system tries to lock a complaint record (or a similar object) identified by the placeholder &1 (which will be replaced by the actual complaint number or ID), but the lock cannot be obtained. This usually happens because:
  
  The complaint is already locked by another user or process.
  A previous lock was not released properly due to a system crash or an incomplete transaction.
  There is a deadlock situation or a long-running transaction holding the lock.
  The complaint object is currently being processed in another session or background job.
  
  What does locking mean in SAP?
  Locking is a mechanism to prevent multiple users or processes from changing the same data simultaneously, which could lead to inconsistencies. When a user or process locks an object, others cannot modify it until the lock is released.
  
  Solution / How to resolve:
  
  
  Check who holds the lock:
  
  Use transaction SM12 (Lock Entries) to find the lock entry for the complaint.
  Enter the complaint number or relevant object key in the selection screen.
  Identify the user or process holding the lock.
  
  
  
  If the lock is held by an active user:
  
  Contact the user to finish their work and release the lock.
  If the user is not available or the session is inactive, you may consider terminating the session (use transaction SM04 or AL08 to check user sessions).
  
  
  
  If the lock is stale or orphaned:
  
  You can manually delete the lock entry in SM12 if you are sure no active process is using it.
  Be cautious when deleting locks to avoid data inconsistencies.
  
  
  
  Check for long-running or stuck background jobs:
  
  Use SM37 to check for jobs that might be holding the lock.
  Cancel or restart jobs if necessary.
  
  
  
  Review custom code or enhancements:
  
  If this error occurs frequently, check if there is custom code or user exits that lock the complaint but do not release the lock properly.
  Ensure proper lock handling (lock and unlock) in the code.
  
  
  
  System performance and deadlocks:
  
  Investigate if system performance issues or deadlocks are causing locks to be held longer than usual.
  Work with your Basis team to analyze and resolve such issues.
