Events Definition in Adobe Interactive Form

Hi,

I have a requirement to define a Button and handle the appropiate action in my BADI.

I found out the appropiate BADI's method(SCENARIO_PROCESS_USER_COMMAND).I can include my coding here based on the USER COMMAND value.

Now, I would like the define the Function code Value(User Command Value) for my button in my Adobe Interactive Form.

Can anyone let us know how this can be done?

Regards,
