Add a popup screen when executing IW33(Service Order) and IW53(Notification)

Hello SCN,

I have a requirement whereby when a user opens a service order or a service notification, a pop-up screen is displayed with some specific info about the sold-to-party.  The pop-up should display in the PAI after executing the tcode IW33 or IW53.

I checked the package for both tcodes IW53(IWOC) and IW33(IWO2) but couldn't find a suitable exit in order to implement this feature.

Please help

Kind regards

Thyaga
