Hi

Your flow screen should be like this:

PROCESS PBO.

MODULE INIT_PAGE.

LOOP.

MODULE READ_ITAB.

ENDLOOP.

PROCESS PAI.

LOOP.

MODULE GET_ROWS_DISPLAED.

MODULE MODIFY_ITAB.

ENDLOOP.

MODULE GET_TOT_LINE.

-

---

MODULE INIT_PAGE.

IF TOP_LINE = 0.

TOP_LINE = 1.

ENDIF.

ENDMODULE.

MODULE READ_ITAB.

CURSOR = TOP_LINE + SY-STEPL - 1.

READ TABLE ITAB INDEX CURSOR.

IF SY-SUBRC <> 0.

CLEAR ITAB.

ENDIF.

ENDMODULE.

-

---

MODULE GET_TOT_LINE.

DESCRIBE TABLE ITAB LINES TOT_LINE.

ENDMODULE.

MODULE GET_ROWS_DISPLAED.

DISP_LINE = SY-LOOPC.

ENDMODULE.

MODULE MODIFY_ITAB.

CURSOR = TOP_LINE + SY-STEPL - 1.

MODIFY ITAB INDEX CURSOR.

ENDMODULE.

MODULE USER_COMMAND.

MODULE USER_COMMAND.

CASE OK_CODE.

WHEN 'PG_DW'.

TOP_LINE = TOP_LINE - DISP_LINE.

IF TOP_LINE < 1. TOP_LINE = 1. ENDIF.

WHEN 'PG_UP'.

TOP_LINE = TOP_LINE + DISP_LINE.

IF TOP_LINE > DISP_LINE. TOP_LINE = DISP_LINE. ENDIF

ENDCASE.

ENDMODULE.

Hi,

Check the SAP Standard Program :

<b>DEMO_DYNPRO_TABCONT_LOOP</b>.

Code :

CONTROLS flights TYPE TABLEVIEW USING SCREEN 100.

DATA: ok_code TYPE sy-ucomm,

save_ok TYPE sy-ucomm.

DATA: itab TYPE TABLE OF demo_conn,

fill TYPE i.

TABLES demo_conn.

DATA: lines TYPE i,

limit TYPE i.

SELECT * FROM spfli INTO CORRESPONDING FIELDS OF TABLE itab.

CALL SCREEN 100.

MODULE status_0100 OUTPUT.

SET PF-STATUS 'SCREEN_100'.

DESCRIBE TABLE itab LINES fill.

flights-lines = fill.

ENDMODULE.

MODULE fill_table_control OUTPUT.

READ TABLE itab INTO demo_conn INDEX flights-current_line.

ENDMODULE.

MODULE cancel INPUT.

LEAVE PROGRAM.

ENDMODULE.

MODULE read_table_control INPUT.

lines = sy-loopc.

MODIFY itab FROM demo_conn INDEX flights-current_line.

ENDMODULE.

MODULE user_command_0100 INPUT.

save_ok = ok_code.

CLEAR ok_code.

CASE save_ok.

WHEN 'NEXT_LINE'.

flights-top_line = flights-top_line + 1.

limit = fill - lines + 1.

IF flights-top_line > limit.

flights-top_line = limit.

ENDIF.

WHEN 'PREV_LINE'.

flights-top_line = flights-top_line - 1.

IF flights-top_line < 0.

flights-top_line = 0.

ENDIF.

WHEN 'NEXT_PAGE'.

flights-top_line = flights-top_line + lines.

limit = fill - lines + 1.

IF flights-top_line > limit.

flights-top_line = limit.

ENDIF.

WHEN 'PREV_PAGE'.

flights-top_line = flights-top_line - lines.

IF flights-top_line < 0.

flights-top_line = 0.

ENDIF.

WHEN 'LAST_PAGE'.

flights-top_line = fill - lines + 1.

WHEN 'FIRST_PAGE'.

flights-top_line = 0.

ENDCASE.

ENDMODULE.

See the Structure <b>CXTAB_CONTROL</b> which has all the attribute of Table Control

Here Top_line is the attribute of CONTROLS or you can say Table Control , Top_line is topmost displayed row for next PBO . Set at time of PAI by the position of the vertical slider box.
