User exit variable problem...

Hi Guys,

I have an ISTEP 2 requirement. I am not good in abap. Please tell me exact code for below logic.

My requirement:

One variable V1 (0P_KEYDT) is populating todays date or user can enter any dates. I need to catch that and pass it to another dummy variable V2 (date). I am going to create formula variable on V2 and use it for some other boolean logic in a formula.

Can anybody tell me exact code for reading one variable date and assigning it to other as per above logic.

Appreciate your help.

Thanks.
