• What is the cause and solution for SAP error message COV_LOG085 - RSCVR_COLLECT: Data cannot be merged (ENQUEUE error: &1) ?

  The SAP error message COV_LOG085 indicates that there is an issue with data merging in the context of the RSCVR_COLLECT function, specifically due to an enqueue error. This typically means that the system is unable to access a resource because it is locked by another process. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Enqueue Lock: The error is primarily caused by an enqueue lock on the data that the system is trying to access. This can happen if another user or process is currently working with the same data set, preventing your process from obtaining the necessary lock to proceed.
  Long-running Transactions: If a transaction is taking too long to complete, it may hold onto locks longer than expected, causing other processes to fail when they attempt to access the same data.
  Deadlocks: In some cases, a deadlock situation may arise where two or more processes are waiting for each other to release locks, leading to this error.
  
  Solution:
  
  Identify the Lock: Use transaction code SM12 to check for existing locks. You can filter by user or object to find out which process is holding the lock.
  Release the Lock: If you identify a lock that is no longer needed (e.g., a user session that has been terminated), you can manually delete the lock entry from SM12. However, be cautious when doing this, as it may disrupt the other user's work.
  Retry the Operation: After resolving the lock issue, try to rerun the operation that caused the error.
  Optimize Long-running Processes: If you frequently encounter this error due to long-running transactions, consider optimizing those processes to reduce the time they hold locks.
  Check for Deadlocks: If you suspect a deadlock, you may need to analyze the system's performance and transaction logs to identify and resolve the underlying issues.
  
  Related Information:
  
  Transaction Codes:
  
  SM12: To view and manage lock entries.
  SM21: To check the system log for any related errors or warnings.
  ST22: To analyze dumps that may provide more context on the error.
  
  
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. You can search the SAP Support Portal for specific notes that may address your situation.
  Performance Monitoring: Use transaction ST03N to monitor system performance and identify any bottlenecks that may be causing long-running transactions.
  
  By following these steps, you should be able to diagnose and resolve the COV_LOG085 error effectively. If the problem persists, consider reaching out to your SAP Basis team or SAP support for further assistance.
