Screen Enhancements

• An instance of the BADI class must be passed to the user of the BADI to allow that user to get the data to be displayed on the screen.
• For this purpose , the instance is saved in a public static read-only attribute DYNPRO_INSTANCE of the BADI call. This attribute is generated.
• A public static method SET_INSTANCE_FOR_SUBSCREEN sets the attribute on the application side to the parameter passed.
• Using the method GET_INSTANCE_FOR_SUBSCREEN the parameter is then read on the user side.

Note : The Definition of Each screen Enhancement should contain the following.

Methods :

1.  PUT_DATA_TO_SCREEN   :- Transport Data to the Subscreen
2. GET_DATA_FROM_SUBSCREE :- Transport Data from screen.
3. And one more method (DESCRIBE ) to provide the details of the Module pool program and sub-screen Details.
