Hi,

Follow the steps to update the database table records.

1.TOP INCLUDE code

TABLES: EKKO.

DATA: OK_CODE TYPE SY-UCOMM.

CONTROLS: TC100 TYPE TABLEVIEW USING SCREEN 100.

DATA: IT_EKKO LIKE EKKO OCCURS 0 WITH HEADER LINE.

DATA: CUR TYPE I.

DATA: I_EKKO2 LIKE EKKO OCCURS 0 WITH HEADER LINE.

DATA: V_FNAM TYPE I,V_FVAL(10) TYPE N.

2.Create screen with number(e.g 123) and click on layout tab

Give the table control name as TC100.

SELECT THE FIELDS FROM INTERNAL TABLE (IT_EKKO). DRAG THE TEXT FIELDS INTO THE TABLE CONTROL FOR FIELD HEADINGS.

Create 4 pushbuttons(insert,fetch,delete and exit)

CLICK ON “Element list” TAB AND ENTER THE “OK_CODE”.

CLICK ON FLOWLOGIC TAB.

3.Flowlogic code

PROCESS BEFORE OUTPUT.

MODULE STATUS_0100.

LOOP AT IT_EKKO CURSOR CUR WITH CONTROL TC100.

ENDLOOP.

PROCESS AFTER INPUT.

LOOP AT IT_EKKO.

MODULE MODIFY_ITAB.

ENDLOOP.

MODULE USER_COMMAND_0100.

4.Double click on MODIFY_ITAB and write as

module MODIFY_ITAB input.

APPEND IT_EKKO TO I_EKKO2.

endmodule. " MODIFY_ITAB INPUT

5.Activate PAI and double click on it and write the code as

module USER_COMMAND_0100 input.

CASE OK_CODE.

WHEN 'INS'.

LOOP AT I_EKKO2.

MODIFY EKKO FROM I_EKKO2.

ENDLOOP.

SELECT * FROM EKKO INTO TABLE IT_EKKO.

IF SY-SUBRC = 0.

MESSAGE S003(ZCSMSG).

ENDIF.

WHEN 'FETCH'.

SELECT * FROM EKKO INTO TABLE IT_EKKO UP TO 2000 ROWS.

TC100-LINES = SY-DBCNT.

WHEN 'EXIT'.

LEAVE PROGRAM.

ENDCASE.

endmodule. " USER_COMMAND_0100 INPUT

6.Create Transaction code and execute it.

Reward,if useful.

Thanks,

Chandu
