OK_CODE does take value

[Former Member]

Hi,

I'm learning Dialog programming. I created a Dialog program to get the Details of a Particular plane on a given date. I also created a GUI STATUS.

As far I know, value in OK_CODE field is set automatically during runtime. I have defined it as follows:

DATA ok_code like sy_ucomm.

The problem is : ok_code value is initial during runtime. There is no value in OKCODE field. When I use sy-ucomm directly, the code works fine.

I need to use EXIT, BACK, and CANCEL buttons. Unable to do so due to this problem.

I have no idea how to over come this. Could any one please help me,

Thanks

Hi,

Have you defined OK_CODE in the screen layout - Element list?

Hi,

I have defined OK_CODE field in the TOP include of the program.

Set the value of OK_CODE field just before, you want to use it. It automatically does not hold any value. So wherever you are performing any operation based on OK_CODE, use this stmt. OK_CODE = SY-UCOMM. and ignore using sy-ucomm directly in your program. And define this OK_CODE field at both places, once in the screen's element list and another in your program.

Hi,

Thank you very much for the reply. I'll try that. Could you please tell how to define OK_CODE field in Screen Element list?

I have defined this field only in TOP Include of the dialog program as follows. DATA ok_code like sy-ucomm.

Go to SE51 and enter your program name and screen number. Dont click on 'Layout' button. There you can see three tabs.. 1. Attributes, 2. Element List, 3. Flow Logic. Click on 2nd Tab.

You need to define this OK_CODE in this under 'General Attributes'.

Sujeet already explained the way how it must be done to work. I only would like to add some useful link which I think you should get familiar with

I will help you to uderstand the concept of saving ok_code .

Thank you very much. Defining the OK_CODE field in the Screen Element List solved the problem.

Full Points awarded to you. Thanks a lot.

Hi Marcin,

Thank you very much for the link. Helped me a lot.

There are 2 methods according to TAW12 material:

1) MODULE clear_okcode OUTPUT.

CLEAR OK_CODE.

ENDMODULE.

2) MODULE clear_okcode INPUT.

save_ok = OK_CODE.

CLEAR OK_CODE.

ENDMODULE.

But they failed to mention that OK_CODE had to be defined in SCREEN Element List as well.

Thanks a lot for the help guys.
