User Indetrface for COR6

Hi Gurus -

We have to create a simple user interface to COR6 For Process order confirmation - say ZCONF

to plug in the yield, and consumption etc.

Whats the best way to create the interface with some mathematical validation and

then, when we save it - COR6 runs behind the seen to post the good movements.

I am a beginner in this area.

Thanks you all!
