To use a subscreen, you must follow three simple steps
Also, you need to adjust the frame of sub-screen and main screen. You need to name it in the field name field.
Further, you also need to adjust the fields within the subscreen to make them appear in main screen. In case the sub-screen is defined to be larger than the available area in the main screen, only the part of subscreen will be visible that fits in the the area available. The area is always measured from the top left corner of screen. Hence you should take adequate care while defining sub-screen areas and creating sub-screens.
EXAMPLE
For instance here we have defined two sub-screen areas on main screen and have attached two different Sub-screen to corresponding areas. Whenever main screen is called, the PBO of main screen is called. But before display, the PBO's of each screen attached with sub-screen areas on main screen are also called.
You can include a subscreen screen using the CALL SUBSCREEN statement in the flow logic of the main screen.
To include a subscreen screen in the subscreen area of the main screen and call its PBO flow logic, use the following statement in the PBO event of the main screen:
PROCESS BEFORE OUTPUT. CALL SUBSCREEN <area> INCLUDING [<prog>] <dynp>.
This statement assigns the subscreen screen with number <dynp> to the subscreen area called <area>. You can also specify the program in which the subscreen screen is defined (optional). If you do not specify the program explicitly, the system looks for the subscreen screen in the same ABAP program as the main program. If it does not find a corresponding subscreen screen, a runtime error occurs. The PBO flow logic of the subscreen screen is also included at the same point. This can call PBO modules of the ABAP program in which the subscreen screen is defined. At the end of the subscreen PBO, the global fields from the program are passed to any identically-named screen fields in the subscreen screen. The PBO flow logic of the subscreen screen can itself include further subscreens.
The name <area> of the subscreen area must be entered directly without inverted commas. You can specify the names <prog> and <dynp> either as literals or variables. If you use variables, you must declare and fill identically-named variables in the ABAP program. The screen number <dynp> must be 4 characters long. If you do not assign a subscreen screen to an area, it remains empty.
To call the PAI flow logic of the subscreen screen, use the following statement in the PAI flow logic of the main screen:
PROCESS AFTER INPUT. CALL SUBSCREEN <area>.
This statement includes the PAI flow logic of the subscreen screen included in the subscreen area <area> in the PBO event. This can call PAI modules of the ABAP program in which the subscreen screen is defined. Data is transported between identically-named fields in the subscreen screen and the ABAP program either when the PAI event is triggered, or at the corresponding FIELD statements in the PAI flow logic of the subscreen screen.
