User defined screens in Notification 090 Customer sub screen

I would like to create tabs in the notification with user defined fields.

How does one create a Customer sub screen
(customer exit QQM0100) in the notification?

Can one change the standard field descriptions on other screens?

How does one use this customer exit?

Answer:

First of all, create enhancement.

For a normal enhancement these are the usual steps:

1. Create a project in CMOD and assign enhancement QQM0100;

2. Check in SMOD for function module/component in QQM0100;

3. Create your Z***** include for function module in SE37;

4. Go to CMOD again and activate project;

The second step is to change the field description.

To change standard descriptions in 40b: CMOD > Text Enhancements -> Keywords > Change;

You might need to force the screen to be updated by re- generating the screen in SE51 pressing Ctrl+F3.
