• What is the cause and solution for SAP error message DBMAN373 - Fact table &1 already locked by another process ?

  The SAP error message DBMAN373 indicates that a fact table (in this case, identified by &1) is currently locked by another process. This typically occurs in the context of data loading or data processing in SAP BW (Business Warehouse) or SAP HANA environments, where multiple processes may attempt to access or modify the same data simultaneously.
  Cause:
  
  Concurrent Processes: Another data load or process is currently running that has locked the fact table to ensure data integrity.
  Long-Running Transactions: A previous transaction may be taking longer than expected, holding the lock on the table.
  Deadlocks: In some cases, a deadlock situation may arise where two processes are waiting for each other to release locks.
  System Configuration: Configuration settings related to locking mechanisms may also contribute to this issue.
  
  Solution:
  
  
  Identify the Locking Process:
  
  Use transaction codes like SM12 (for lock entries) to identify which user or process is holding the lock on the fact table.
  Check the process list in transaction SM66 to see if there are any long-running jobs that might be causing the lock.
  
  
  
  Wait and Retry:
  
  If the locking process is legitimate and expected (e.g., a scheduled data load), wait for it to complete and then retry your operation.
  
  
  
  Terminate the Locking Process:
  
  If you determine that the locking process is stuck or not responding, you may need to terminate it. This can be done through transaction SM37 (for job monitoring) or SM12 (for lock entries). Be cautious with this approach, as it may lead to data inconsistencies.
  
  
  
  Review and Optimize Processes:
  
  Analyze the processes that are causing locks and optimize them if necessary. This could involve scheduling data loads during off-peak hours or breaking down large data loads into smaller batches.
  
  
  
  Check System Configuration:
  
  Review the locking configuration in your SAP system to ensure it is set up correctly. Consult with your Basis team if necessary.
  
  
  
  Related Information:
