Screen Exit unable to copy screen functionality fully

[Former Member]

Hi Experts,

My requirement is to copy "Assignment" tab from claim(tcode-clm1) to "Reference object " tab in Notification(t code iw21) My problem is the functionalities are not fully copied(WBS Element) I followed "screen Exit" method step 1: I copied the claim screen(screen no - 7820) and created a new custom screen(ex.scr no 102) through ( t code se51) step 2: using "cmod" transaction i wrote function exit logics and in" spro" config i have added the custom and successfully copied screen and is visible in iw21.

I enter a value for WBS element through search help, then project def. value is filled up automatically and some cost related pop ups are coming by default. But in Notification screen, in which i copied these screen through above method, when i enter a value in WBS element, nothing happens. how to copy these native functionality? please help me with a solution

Thanks
