Using select option in a tabstrip

Hello everyone,

I have a common issue regarding working with a select option in a tabstrip. I did search many threads but I still didnt come to a solution to this particular issue.

The main issue is that I want to include select-option in one of the tabstrips in my module pool program. The select option should look like a normal select option as we see in a report:

After the user enters the sales order and presses "Enter", the a table control should be displayed below in the tabstrip.

I can do this in a normal screen, but how shall I implement the logic in a tabstrip subscreen ? I need to know the steps.

Manish.
