Hello Veena,
- You need to create different subscreens to be used keeping in mind the different Notification Types. (Creation of Subcreens using screen exits in QQMA0001 user-exit)
- Then through SPRO configuration of the respective Notification type you'll assign these subscreens to the the Tab areas you want.
- A very detailed process is documented here for your requirement. User-Fields in QM and PM/CS Notifications : Screen-Exit QQMA0001
Good luck
