abap last row in loop

To retrieve the last row in a loop in ABAP, you can use the LOOP AT ... ENDLOOP statement along with the END OF addition. Here's an example:

DATA: lt_table TYPE TABLE OF string,
      lv_last_row TYPE string.

APPEND 'Row 1' TO lt_table.
APPEND 'Row 2' TO lt_table.
APPEND 'Row 3' TO lt_table.

LOOP AT lt_table INTO lv_last_row.
  IF sy-tabix = lines( lt_table ).
    WRITE: / 'Last row:', lv_last_row.
  ENDIF.
ENDLOOP.

In this example, we have a table lt_table with three rows. The LOOP AT lt_table INTO lv_last_row statement iterates through each row of the table. The IF sy-tabix = lines( lt_table ) condition checks if the current row is the last row by comparing the system field sy-tabix (which represents the current loop index) with the total number of lines in the table lines( lt_table ). If it is the last row, the value of lv_last_row is displayed using the WRITE statement.

Please note that the example provided is a simplified version to demonstrate the concept. In a real-world scenario, you would typically have more complex logic within the loop.
