• What is the cause and solution for SAP error message SALV_X_API025 - Source data was changed without notification ?

  The SAP error message SALV_X_API025 ("Source data was changed without notification") typically occurs in the context of using the SAP ALV (ABAP List Viewer) framework, particularly when working with the SALV (Simple ALV) classes. This error indicates that the underlying data source for the ALV grid has been modified after it was initially read, and the ALV framework is not aware of these changes.
  Cause:
  
  Data Modification: The data in the internal table or data source that the ALV grid is displaying has been changed after the ALV object was created. This can happen if the data is modified in the program without notifying the ALV framework.
  Concurrency Issues: If multiple processes or threads are accessing and modifying the same data, it can lead to inconsistencies.
  Improper Handling of Data: If the data is not properly managed or if the ALV grid is not refreshed after changes, this error can occur.
  
  Solution:
  
  Refresh the ALV Grid: After making changes to the underlying data, ensure that you refresh the ALV grid. You can do this by calling the appropriate methods to refresh or re-display the data.
  DATA(lo_alv) = NEW cl_salv_table( ... ).
  lo_alv->display( ).
  
  Reinitialize the ALV: If the data has changed significantly, consider reinitializing the ALV object with the updated data.
  Use Proper Data Handling: Ensure that any modifications to the data are done in a controlled manner, and that the ALV is notified of these changes. This may involve using methods provided by the ALV framework to update the data.
  Check for Concurrency: If your application is multi-threaded or involves multiple users, ensure that data access is properly synchronized to avoid conflicts.
  
  Related Information:
  
  ALV Documentation: Review the SAP documentation for the ALV framework, particularly the sections on data handling and refreshing the display.
  Debugging: Use debugging tools to trace where the data is being modified and ensure that the ALV is aware of these changes.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on handling ALV data changes.
  
  By following these steps, you should be able to resolve the SALV_X_API025 error and ensure that your ALV grid displays the correct and updated data.
