Hi Uday,

If you specify the name of the database table directly, the program must contain a corresponding TABLES statement. If the name of the database table is not determined until runtime, you need to use the addition ... FROM wa.

MODULE finalise.

MODULE finalise INPUT.

IF sy-dynnr = '0200'..

IF ok_code = 'SAVE'.

PERFORM refresh_screen_200.

PERFORM save_screen_200.

endif.

FORM save_screen_200.

Tables : zvtrans .

Zvtrans-pkey = wf_pkey. "Also u should update ZVTRANS work area with PK values to modify the current line

zvtrans-zsdate = zvtrans-zsdate.

MODIFY zvtrans.

endform.

hi,

check before using the modify statement the keyfields are there in your work area.

And also the subroutine refresh_screen_200 is called before

PERFORM save_screen_200.

just check it.

Hi,

Try this code

in flow logic : pbo

loop at itab into <tn> with -

---

(table contol)

endloop.

pai

loop at itab.

module update

endloop.

in pai : case sy-ucom.

when ' ....'.

update<tn> from table <itabname>.

end case.

<tn>=table name.
