• What is the cause and solution for SAP error message RSREQARCH020 - Lock not retained for table & ?

  The SAP error message RSREQARCH020 indicates that a lock on a specific table could not be retained during the archiving process. This typically occurs in the context of data archiving in SAP BW (Business Warehouse) or other SAP systems where data is being moved from the active database to an archive.
  Cause:
  The error can be caused by several factors, including:
  
  
  Long-running Transactions: If there are long-running transactions that hold locks on the table, the archiving process may not be able to retain the lock it needs to proceed.
  
  
  Database Lock Conflicts: Other processes or users may be accessing the same table, leading to conflicts in lock retention.
  
  
  System Performance Issues: If the system is under heavy load, it may not be able to maintain the necessary locks for the duration of the archiving process.
  
  
  Configuration Issues: There may be configuration settings in the archiving process that are not optimal, leading to lock retention issues.
  
  
  Solution:
  To resolve the RSREQARCH020 error, you can take the following steps:
  
  
  Check for Active Processes: Use transaction codes like SM12 (to check for locks) and SM66 (to monitor active processes) to identify any long-running transactions or processes that may be holding locks on the table.
  
  
  Optimize Archiving Jobs: Schedule archiving jobs during off-peak hours when there are fewer users and processes accessing the system. This can help reduce lock contention.
  
  
  Increase Timeout Settings: If applicable, consider increasing the timeout settings for locks in the system configuration to allow more time for the archiving process to complete.
  
  
  Review Archiving Configuration: Ensure that the archiving configuration is set up correctly. Check the settings in transaction SARA (Archive Administration) for any misconfigurations.
  
  
  Database Performance Tuning: If the database is under heavy load, consider performance tuning measures to improve overall system performance, which may help with lock retention.
  
  
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
