Former Member — Thu, 07 Jun 2007 10:40:33 GMT

Hi,

I have created a ztable declaring the fields as zempname,zempsal,zdeptno.

Again I have written a module pool with these fields.

In that screen i have given 3 push buttons ..SAVE,UPDATE and EXIT.

When I click on save button It must save and When i Click on Update it must update to ztable...I have written code as follows:-

case sy-ucomm

when 'save'

CODE

when 'update'

CODE.

when exit.

leave to screen 0.

endcase.

Please send that CODE.

With Regards,

Srikanth.M

Hi,

when save.

collect the neccessay field in a structure

zstructure will be smae structure as of your ztable.

zstructure-zempname = g_zempname.

zstructure-zempsal = g_empsa.

zstructure-zdeptno = g_deptno.

now modify ztable from zstructure.

when update.

zstructure-zempname = g_zempname.

zstructure-zempsal = g_empsa.

zstructure-zdeptno = g_deptno.

update ztable from zstructure.

endcase.

hi srikanth,

just check this code u can get the answer,

select item material amount from zekpo into corresponding fields of table

g_itab_pur where porder = zekko-porder.

case sy-ucomm.

when 'DISPLAY'.

read table g_itab_pur with key porder = zekko-porder.

endif.

create a z table(ZDEPT) with the fields

zempname,zempsal,zdeptno

so you have to use some STrutrure like XTAB with this 3 fields which you have used on the screen.

SO now you enter data on screen to these fields.

for SAVE and UPDATE it is the same code you can use

it has to save in the table

when 'SAVE' or 'UPDT' (use 4 letter CAPITAL Function Code)

ZDEPT-zempname = XTAB-zempname.

ZDEPT-zempsal = XTAB-zempsal.

ZDEPT-zdeptno = XTAB-zdeptno.

MODIFY ZTAB.

see the sample program:

REPORT ZBHMOD1 .

DATA:OKCODE1 LIKE SY-UCOMM,

OKCODE2 LIKE SY-UCOMM.

DATA:N1(10) TYPE N,N2(10) TYPE N,RES(12) TYPE N.

MODULE USER_COMMAND_1000 INPUT.

CASE OKCODE1.

WHEN 'NEXT'.

RES = N1 + N2.

SET SCREEN 1001.

WHEN 'CLEA'.

SET SCREEN '0'.

*************************************************************

Every Screen has a pbo and a pai.

Screen elements are the textbox, buttons, radio buttons and check boxes .....

If we want to pass data from a abap program to a screen element, we have to create a variable with the name we have given in the screen.So whatever the value is present in that variable is reflected on to the screen element.

Here is an example :

Using subscreens and some of the screen elements

REPORT demo_dynpro_subscreens.

DATA: ok_code TYPE sy-ucomm,

save_ok TYPE sy-ucomm.

DATA: number1(4) TYPE n VALUE '0110',

number2(4) TYPE n VALUE '0130',

field(10) TYPE c, field1(10) TYPE c, field2(10) TYPE c.

ENDMODULE.

MODULE fill_0110 OUTPUT.

ENDMODULE.

MODULE fill_0120 OUTPUT.

field = field1.

ENDMODULE.

MODULE fill_0130 OUTPUT.

field = 'Eingabe 2'(002).

ENDMODULE.

MODULE fill_0140 OUTPUT.
