• What is the cause and solution for SAP error message AQ126 - Unable to delete InfoSets & at present (locked by &) ?

  The SAP error message AQ126, which states "Unable to delete InfoSets & at present (locked by &)," typically occurs when you attempt to delete an InfoSet that is currently locked by another user or process. This locking mechanism is in place to prevent data inconsistencies and ensure that multiple users do not make conflicting changes at the same time.
  Cause:
  
  Lock by Another User: Another user is currently using or has locked the InfoSet you are trying to delete.
  Background Jobs: A background job or process is currently accessing the InfoSet.
  Transaction in Progress: A transaction that involves the InfoSet is still in progress, preventing deletion.
  System Lock: The InfoSet may be locked due to system-level constraints or issues.
  
  Solution:
  
  
  Identify the Lock:
  
  Use transaction code SM12 to check for locks. You can filter by the user or the object type to find out who is locking the InfoSet.
  If you find a lock that is no longer needed, you can ask the user to release it or, if necessary, you can delete the lock yourself (ensure you have the appropriate authorizations).
  
  
  
  Wait for Release:
  
  If the lock is legitimate and necessary, you may need to wait until the user or process releases the lock.
  
  
  
  Check Background Jobs:
  
  Use transaction code SM37 to check for any background jobs that might be using the InfoSet. If you find any, you may need to wait for them to complete or cancel them if they are no longer needed.
  
  
  
  Consult with the User:
  
  If you identify the user who has locked the InfoSet, you can communicate with them to understand why the lock is in place and if they can release it.
  
  
  
  System Administrator:
  
  If you are unable to resolve the issue, consult with your SAP Basis or system administrator for further assistance. They may have additional tools or permissions to resolve the lock.
