• What is the cause and solution for SAP error message 00098 - Program error with LOOP AT int. tab: FROM greater than TO ?

  The SAP error message "00098 Program error with LOOP AT int. tab: FROM greater than TO" typically occurs when there is an issue with the internal table being processed in a LOOP statement. This error indicates that the range specified for the LOOP AT statement is invalid, specifically that the starting index (FROM) is greater than the ending index (TO).
  Cause:
  
  
  Invalid Indexing: The error arises when the internal table is being looped over, and the specified range for the loop is incorrect. This can happen if:
  
  The internal table is empty, and an attempt is made to loop over it with a specified range.
  The FROM index is set to a value greater than the TO index.
  There is a logical error in the code that calculates the indices.
  
  
  
  Data Manipulation: If the internal table is modified (e.g., rows are deleted) before the LOOP statement, it may lead to an invalid range.
  
  
  Solution:
  
  
  Check Index Values: Review the code where the LOOP AT statement is defined. Ensure that the FROM and TO indices are correctly set and that FROM is less than or equal to TO.
  Example:
  DATA: lt_table TYPE TABLE OF your_structure,
        lv_from  TYPE i,
        lv_to    TYPE i.
  
  lv_from = 1.
  lv_to = lines( lt_table ). " Ensure this is valid
  
  LOOP AT lt_table INTO DATA(ls_row) FROM lv_from TO lv_to.
    " Your processing logic here
  ENDLOOP.
  
  
  Handle Empty Tables: Before executing the LOOP, check if the internal table is empty. If it is, avoid executing the loop or set appropriate default values for the indices.
  Example:
  IF lines( lt_table ) > 0.
    LOOP AT lt_table INTO DATA(ls_row).
      " Your processing logic here
    ENDLOOP.
  ELSE.
    " Handle the case where the table is empty
  ENDIF.
  
  
  Debugging: Use the debugger to step through the code and inspect the values of the indices and the internal table before the LOOP statement. This can help identify where the logic may be going wrong.
  
  
  Review Logic: If the indices are calculated dynamically, ensure that the logic used to determine these indices is correct and accounts for all possible scenarios.
  
  
  Related Information:
  
  ABAP Documentation: Review the ABAP documentation for the LOOP statement and internal tables to understand the expected behavior and constraints.
  Error Handling: Implement error handling to gracefully manage situations where the internal table may not contain the expected data.
  Performance Considerations: When working with large internal tables, consider performance implications and optimize the loop logic as necessary.
  
  By following these steps, you should be able to resolve the error and ensure that your LOOP AT statements function correctly.
