• What is the cause and solution for SAP error message >2145 - Items skipped due to conflicting lock: &1 ?

  The SAP error message 2145: "Items skipped due to conflicting lock: &1" typically occurs when a user attempts to process a transaction that involves items that are currently locked by another user or process. This can happen in various scenarios, such as during inventory management, sales order processing, or any other transaction that requires access to specific data records.
  Cause:
  
  Concurrent Access: Another user or process is currently accessing or modifying the same data records that you are trying to work with.
  Locking Mechanism: SAP uses a locking mechanism to prevent data inconsistencies. When a record is locked, other users cannot modify it until the lock is released.
  Long-running Transactions: If a transaction takes a long time to complete, it can lead to locks being held for extended periods, causing other users to encounter this error.
  
  Solution:
  
  Wait and Retry: Often, the simplest solution is to wait for a few moments and then retry the transaction. The lock may be released once the other user or process completes their transaction.
  Identify the Lock: Use transaction code SM12 to check for existing locks. You can see which user or process is holding the lock on the specific item. If necessary, you can contact the user to resolve the issue.
  Lock Management: If you have the necessary authorizations, you can manually delete the lock entries in SM12, but this should be done with caution as it may lead to data inconsistencies.
  Optimize Processes: If this error occurs frequently, consider reviewing and optimizing the processes that lead to long locks. This may involve improving transaction performance or scheduling tasks to minimize conflicts.
  User Training: Ensure that users are trained on how to properly manage transactions to avoid unnecessary locks.
  
  Related Information:
  
  Transaction Codes:
  
  SM12: Display and manage lock entries.
  SM21: Check system logs for any related issues.
  SM37: Monitor background jobs that may be causing locks.
  
  
  SAP Notes: Check SAP Notes for any known issues or patches related to locking behavior in your specific version of SAP.
  Performance Monitoring: Regularly monitor system performance and user activity to identify patterns that may lead to locking issues.
  
  If the problem persists after trying the above solutions, it may be beneficial to consult with your SAP Basis team or SAP support for further assistance.
