• What is the cause and solution for SAP error message PSM_S4C_FM_AVC002 - Exclusive enqueue failed ?

  The SAP error message PSM_S4C_FM_AVC002: Exclusive enqueue failed typically occurs in the context of the SAP system when there is an issue with locking mechanisms, particularly when trying to access or modify a resource that is already locked by another process. This can happen in various scenarios, such as during financial transactions, budget management, or when working with funds management.
  Causes:
  
  Concurrent Access: Another user or process is currently accessing the same resource, leading to a lock conflict.
  Long-Running Transactions: A transaction that takes too long to complete may hold a lock longer than expected, preventing other transactions from proceeding.
  System Configuration: Incorrect configuration of the locking mechanism or enqueue settings in the SAP system.
  Deadlocks: Situations where two or more processes are waiting for each other to release locks, causing a deadlock.
  
  Solutions:
  
  Wait and Retry: If the error is due to concurrent access, waiting for a short period and then retrying the operation may resolve the issue.
  Identify Locking Process: Use transaction codes like SM12 (Display and Delete Locks) to identify which user or process is holding the lock. You can then decide whether to wait for it to complete or, if appropriate, release the lock.
  Optimize Transactions: Review and optimize long-running transactions to ensure they complete more quickly and release locks sooner.
  Check Configuration: Ensure that the enqueue settings and configurations are correctly set up in the SAP system. Consult with your SAP Basis team if necessary.
  Monitor for Deadlocks: Use transaction SM21 (System Log) to check for deadlocks and analyze the logs to identify the root cause.
  Increase Lock Timeout: If applicable, consider increasing the lock timeout settings to allow longer wait times for locks to be released.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SM12 (to view locks), SM21 (to view system logs), and SM37 (to monitor background jobs).
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP frequently updates its knowledge base with solutions for common problems.
  User Training: Ensure that users are trained on how to handle transactions that may lead to locking issues, including best practices for completing transactions efficiently.
