SAP sm30 brings out description or custom logical relationship

The two methods , One is to use SE38 Programming ,
The other is to write directly on the maintenance view screen .
The latter is relatively simple .
1. Go first se11 Maintenance table view
2. And then in se93 Create transaction code
3. then se80 Find the function group used for maintenance
4. Found in the se11 Search screen number of , Write relevant logic code in the screen number

The first one is

0.se11 Maintain database tables

1. Create transaction code

2. As shown in the figure

3.se80 Find yourself in se11 Maintain the function group selected in the view

4. stay PAI Custom logical processing can be added to the event

**5. Just write the code below **

Here you can edit your field header text

Here you can control whether the field is inputable

The second method

Mainly use these two functions
VIEW_RANGETAB_TO_SELLIST
VIEW_MAINTENANCE_CALL
