• What is the cause and solution for SAP error message BKK_OPD_MSG134 - Child enqueue failed, package is skipped) (grouping criteria: &1) ?

  The SAP error message BKK_OPD_MSG134 ("Child enqueue failed, package is skipped") typically occurs in the context of the SAP Bank Communication Management (BCM) or similar financial transaction processing scenarios. This error indicates that the system was unable to acquire a lock (enqueue) on a specific object or resource, which is necessary for processing a transaction or operation. As a result, the package of transactions is skipped.
  Causes:
  
  Lock Contention: Another process or user may already have a lock on the resource that the current transaction is trying to access. This can happen in high-volume environments where multiple transactions are being processed simultaneously.
  Long-running Transactions: If a transaction takes too long to complete, it may hold onto locks longer than expected, causing subsequent transactions to fail to acquire the necessary locks.
  Configuration Issues: Incorrect configuration of the enqueue server or related settings may lead to issues in acquiring locks.
  System Performance Issues: If the system is under heavy load or experiencing performance issues, it may not be able to handle enqueue requests efficiently.
  
  Solutions:
  
  Identify Lock Holders: 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 the lock to be released or take action to release it.
  Optimize Transactions: Review and optimize long-running transactions to ensure they complete more quickly and release locks sooner.
  Increase System Resources: If the system is under heavy load, consider increasing resources (CPU, memory) or optimizing the database to improve performance.
  Review Configuration: Check the configuration of the enqueue server and ensure that it is set up correctly. This may involve consulting with your SAP Basis team.
  Retry Logic: Implement retry logic in your application or process to handle transient lock failures gracefully.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SM12 (to view locks), SM21 (to check system logs), and ST22 (to check dumps).
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide guidance on best practices for handling enqueue issues.
  Performance Monitoring: Use tools like ST03N (Workload Analysis) to monitor system performance and identify bottlenecks that may be contributing to lock contention.
