Smart SAP Assistant

• What is the cause and solution for SAP error message S04118 - &1 : Request enqueue for &2 ?

  The SAP error message S04118 typically indicates that there is an issue with the enqueue mechanism in the SAP system. This error occurs when a request cannot be processed because the enqueue lock for a specific object is not available. The message format is usually as follows:
  S04118 &1 : Request enqueue for &2
  Where &1 represents the specific request or object, and &2 represents the name of the object that is being locked.
  Causes:
  
  Lock Contention: Another process or user is holding a lock on the object, preventing your request from acquiring the necessary lock.
  Long-running Transactions: A transaction that takes too long to complete may hold locks longer than expected, causing other requests to fail.
  System Performance Issues: High system load or performance issues can lead to delays in lock acquisition.
  Configuration Issues: Incorrect configuration of the enqueue server or related settings may lead to locking issues.
  
  Solutions:
  
  
  Identify the Lock Holder:
  
  Use transaction SM12 to check for existing locks. You can see which user or process is holding the lock on the object.
  If you find a lock that is no longer needed, you can delete it (if you have the necessary authorizations).
  
  
  
  Check for Long-running Transactions:
  
  Use transaction SM50 or SM66 to monitor active processes and identify any long-running transactions that may be holding locks.
  If you find a transaction that is stuck, you may need to terminate it (with caution).
  
  
  
  Review System Performance:
  
  Check system performance metrics to ensure that the system is not overloaded. You may need to optimize performance or increase resources.
  
  
  
  Configuration Review:
  
  Review the configuration of the enqueue server and ensure that it is set up correctly. This may involve checking parameters in the instance profile.
  
  
  
  Retry the Request:
  
  Sometimes, simply retrying the request after a short period can resolve the issue if the lock was temporary.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
