• What is the cause and solution for SAP error message DBMAN370 - Summarization not possible during change run ?

  The SAP error message DBMAN370: Summarization not possible during change run typically occurs in the context of data summarization processes, particularly when working with data in the SAP BW (Business Warehouse) or SAP ERP systems. This error indicates that the system is unable to perform a summarization operation because a change run is currently in progress.
  Cause:
  
  Active Change Run: The most common cause of this error is that a change run is currently active. Change runs are processes that update data in the database, and during this time, summarization cannot be performed to ensure data integrity.
  Locking Mechanism: SAP uses a locking mechanism to prevent data inconsistencies. If a change run is in progress, the system locks the relevant data, preventing summarization.
  Configuration Issues: There may be configuration settings that are not aligned correctly, leading to this error.
  
  Solution:
  
  Wait for Change Run to Complete: The simplest solution is to wait until the current change run has completed. You can monitor the status of the change run in the relevant transaction (e.g., RSA1 for BW).
  Check for Long-Running Processes: If the change run is taking an unusually long time, investigate the process to ensure it is functioning correctly. You can check the job logs in transaction SM37 to see if there are any issues.
  Restart the Change Run: If the change run seems to be stuck, you may need to cancel it and restart it. Be cautious with this approach, as it may lead to data inconsistencies if not handled properly.
  Review Configuration: Check the configuration settings related to the summarization and change run processes to ensure they are set up correctly.
  Consult SAP Notes: Look for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSA1 (Data Warehousing Workbench), SM37 (Job Monitoring), and ST22 (Dump Analysis) for troubleshooting.
  SAP Documentation: Refer to the official SAP documentation for detailed information on summarization processes and change runs.
  Performance Monitoring: Use tools like ST03N (Workload Analysis) to monitor system performance and identify any bottlenecks that may be affecting the change run.
  
  If the issue persists after trying the above solutions, it may be beneficial to reach out to your SAP Basis or BW support team for further assistance.
