  Causes:
  
  Table Declaration Issues: The internal table may not be declared correctly, or it may not have the appropriate structure defined.
  Index Out of Range: The program may be trying to access or modify an index in the internal table that does not exist (e.g., trying to access an index that is greater than the number of entries in the table).
  Locking Issues: If the internal table is being modified while it is being accessed by another process, it may lead to conflicts.
  Data Type Mismatch: There may be a mismatch between the data types of the fields in the internal table and the data being assigned to them.
  Invalid Operations: Attempting to perform operations that are not allowed on the internal table, such as modifying a read-only table.

  Check Table Declaration: Ensure that the internal table is declared correctly with the appropriate structure. Verify that the data types of the fields match the expected types.
  DATA: lt_table TYPE TABLE OF your_structure.
  
  
  Validate Index Access: Before accessing or modifying an index, check that the index is within the valid range. Use the LINES() function to determine the number of entries in the table.
  IF index <= lines( lt_table ).
      " Perform modification

      " Handle error
  ENDIF.
  
  
  Review Locking Mechanisms: If the internal table is being accessed by multiple processes, consider implementing proper locking mechanisms to prevent conflicts.
