Combining different IT screens in one screen for PA20

Hello Friends,

I am working on getting different IT screens from PA20 into one screen and it is directly going into PA20 IT0001 screen.

I am trying to get values from IT0001 for Position, Position text, Org Unit, Org Unit Text, Job Code

And also clarify on below doubt.

1. When I enter emp # and click on find, it shows employee name and again click on "empl. info" getting employee cost center, EE Grp, EE Subgrp, PA. When I enter another employee #, is it possible to clear other fields automatically.

Thanks.

Regards,
