Hi,

I have created a screen 100 and there are four fields for the user to input. I need to transfer the data (which the user enters) to the internal table. So that I can compare those data with the database and wants to display a message in the same screen.please tell me how to do it

Hi,

U can acess the values entered by the user in the PAI event. There u can append them in to internal table and compare with the database.

You can display corresponding message on the same screen.

Regards,

Sankar

Hi,

say your flow logic will like this:

PBO:

MODULE PBO_100.

PAI:

MODULE PAI_100.

NOW IN PAI WRITE LIKE

if sy-ucomm = 'SAVE'. "User presses SAVE button
itab-fld1 = tblctrl-tbl_fld1.
itab-fld2 = tblctrl-tbl_fld2.
itab-fld3 = tblctrl-tbl_fld3.
itab-fld4 = tblctrl-tbl_fld4.
append itab.
endif.

"comapre data here

"show message
if <comditon> = <codn>.
message 'type a message' type 'I'. "information message .
endif.

Hope this will help u.

1. first user enters data in the screen

2. get your data from the data base in to a work area

3. wa-fld1 = freld 1 form screen

wa-fld2 = freld 2 form screen

wa-fld3 = freld 3 form screen

wa-fld4 = freld 4 form screen

if all the four conditions are satisfied

set a flag as 'x'

if not display a your message

and use this flag where ever u want these conditions further

First uif u r having the fieldnames of the textbox which u have in ur screen 100 as like table or differesnt...

for example if u have fieldname as i_vbeln i_date then u have to declare in ur program first.

If u are having VBAK-VBELN then no need to declare in the program

Declare in program like this...

Data : i_vbeln like vbak-vbeln.

Then in screen 100

in the PAI

Chain.

field: i_vbeln ,

i_date.

Module Process_fiele.

endchain.

Module Process_fields input.

Check here with the database table.

endmodule.

Hi,

The easiest way is to use a work area(wa) created as:

Data: wa like line of itab.

Afterwards you call wa from screen via get from program tooltipped button and write the textbox wa. Then click ok.

The fields automatically come.

For example the itab and wa contains the fields like, Name, SName,City,Zip.

Then:

In the PAI write:

itab-name = wa-name.

itab-sname = wa-sname.

itab-city = wa-city.

itab-zip = wa-zip..

append itab.

The game is over now:)

Hope helps...
