• What is the cause and solution for SAP error message SALV_X_API097 - Illegal line number for log operation (&1) ?

  The SAP error message SALV_X_API097 Illegal line number for log operation (&1) typically occurs when there is an attempt to access a line number in a log operation that is either out of range or invalid. This error is often associated with the SAP ALV (ABAP List Viewer) framework, particularly when dealing with log operations in the context of ALV grid displays.
  Cause:
  
  Invalid Line Number: The line number specified in the log operation does not correspond to any existing line in the ALV output. This can happen if the line number is less than 1 or greater than the total number of lines displayed.
  Data Manipulation: If there are changes made to the data displayed in the ALV (like filtering or sorting) after the log operation was initiated, the line numbers may no longer be valid.
  Incorrect Logic in Code: There may be a logical error in the ABAP code that calculates or retrieves the line number for the log operation.
  
  Solution:
  
  Check Line Number Validity: Ensure that the line number being referenced in the log operation is valid. It should be within the range of existing lines in the ALV output.
  Debugging: Use the ABAP debugger to trace the execution of the code and check the values of the line numbers being used. This can help identify where the invalid line number is being generated.
  Review Code Logic: Review the logic in your ABAP program to ensure that the line number is being calculated correctly and that it corresponds to the current state of the ALV display.
  Update ALV Display: If the ALV display has been modified (e.g., through filtering or sorting), ensure that any operations that depend on line numbers are updated accordingly.
  Error Handling: Implement error handling in your code to manage cases where an invalid line number might be referenced, providing a fallback or a user-friendly message.
