Time Field on the screen to be populated from the program

Hello Experts,

I have a requirement in which I have a field of type sy-uzeit (on a screen in Module Pool) and this has to be populated from the program after some calculations.

But what I have observed in previous developments is that, a field will be populate on the screen, if it is declared in the database and mapped to this dictionary structure or it is declared of type char.

But here I cant use any of the above solution.

So, Please suggest some other way to achieve this. I have tried all Dynpro update, get/set parameter but did not work.

Thanks in Advance !!

Regards

Vishal Kumar
