• What is the cause and solution for SAP error message PSM_S4C_FM_AVC004 - Shared enqueue failed ?

  The SAP error message PSM_S4C_FM_AVC004: Shared enqueue failed typically occurs in the context of SAP's Financial Management (FM) module, particularly when dealing with budget control and availability checks. This error indicates that there was an issue with acquiring a shared lock (enqueue) on a resource that is necessary for processing a financial transaction.
  Causes:
  
  Concurrency Issues: The error often arises when multiple users or processes are trying to access the same resource simultaneously, leading to a conflict in acquiring the necessary lock.
  Long-running Transactions: If a transaction is taking too long to complete, it may hold onto the lock longer than expected, causing other transactions to fail when they attempt to acquire the same lock.
  System Configuration: Incorrect configuration of the enqueue server or issues with the SAP instance can also lead to this error.
  Database Locks: Sometimes, database-level locks can interfere with the enqueue mechanism, leading to this error.
  
  Solutions:
  
  Retry the Operation: Often, simply retrying the operation after a short wait can resolve the issue, especially if it was caused by a temporary lock.
  Check for Long-running Transactions: Use transaction codes like SM50 or SM66 to monitor active processes and identify any long-running transactions that may be holding locks.
  Review System Logs: Check the system logs (transaction SLG1) for any related error messages that might provide more context on the issue.
  Adjust Lock Timeout Settings: If the issue is frequent, consider adjusting the lock timeout settings in the SAP system to allow for longer wait times before failing.
  Enqueue Server Configuration: Ensure that the enqueue server is properly configured and that there are no issues with the SAP instance that could be causing the lock contention.
  Database Maintenance: Perform regular database maintenance to ensure that there are no underlying issues causing locks at the database level.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SM12 (to view and manage locks), SM21 (to view system logs), and SLG1 (to view application logs).
  SAP Notes: Check SAP Notes for any known issues or patches related to this error. SAP frequently updates its knowledge base with solutions for common problems.
  Performance Monitoring: Regularly monitor system performance and lock statistics to identify patterns that may lead to this error.
