• What is the cause and solution for SAP error message FSH_ARUN_MSG020 - Lock error; sales order &1 locked by user &2 ?

  The SAP error message FSH_ARUN_MSG020 indicates a lock error related to a sales order. Specifically, it means that the sales order identified by &1 is currently locked by another user identified by &2. This typically occurs when multiple users or processes attempt to access or modify the same sales order simultaneously.
  Cause:
  
  Concurrent Access: Another user is currently editing or processing the sales order, which prevents other users from making changes until the lock is released.
  Long-running Transactions: A transaction that takes a long time to complete may hold the lock longer than expected.
  System Configuration: Certain configurations in the SAP system may lead to more frequent locking scenarios, especially in high-transaction environments.
  
  Solution:
  
  Wait and Retry: The simplest solution is to wait for the other user to finish their transaction. Once the lock is released, you can try to access the sales order again.
  Identify the Locking User: If you have the necessary permissions, you can use transaction SM12 to view the locks in the system. This will allow you to see which user is holding the lock and potentially contact them to resolve the issue.
  Release the Lock: If the locking user is no longer active or if the lock is stale (e.g., due to a session timeout), an administrator can manually release the lock using transaction SM12. However, this should be done with caution to avoid data inconsistency.
  Optimize Processes: If lock errors occur frequently, consider reviewing and optimizing the processes that access sales orders to minimize concurrent access. This may involve training users on best practices or adjusting workflows.
  System Configuration Review: Consult with your SAP Basis team to review system configurations and performance. They may be able to adjust settings to reduce locking issues.
