• What is the cause and solution for SAP error message SALV_X_API101 - Number of lines was chanbed since last recording stop ?

  The SAP error message SALV_X_API101 indicates that there has been a change in the number of lines in a table or internal table since the last recording was stopped. This error typically occurs in the context of using the SAP ALV (ABAP List Viewer) or when working with the SALV (SAP ABAP List Viewer) classes.
  Cause:
  
  Data Modification: The number of entries in the internal table or data source has changed due to an operation that added or removed rows.
  Incorrect Data Handling: The data being processed may not be consistent with the expected structure or number of entries.
  Concurrency Issues: If multiple processes are trying to modify the same data, it can lead to discrepancies in the number of lines.
  
  Solution:
  
  Check Data Consistency: Ensure that the data being passed to the ALV or SALV is consistent and has not been modified unexpectedly. You can do this by debugging the program and checking the internal table before it is passed to the ALV.
  Reinitialize the ALV: If the data has changed, you may need to reinitialize the ALV display or refresh the data source to reflect the current state of the data.
  Error Handling: Implement error handling in your code to manage situations where the data might change unexpectedly. This can include checks before displaying the ALV.
  Review Code Logic: Go through the logic of your program to ensure that the data manipulation is done correctly and that the ALV is only called after all data modifications are complete.
  
  Related Information:
  
  ALV Documentation: Review the SAP documentation on ALV and SALV to understand the expected data structures and how to properly handle data.
  Debugging: Use the ABAP debugger to step through the code and monitor the internal tables being used. This can help identify where the data is being modified.
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional guidance on handling ALV displays.
