Define ABAP Subscreens ?

Answer

Subscreens

• A subscreen is an independent screen that is displayed in an area of another ("main") screen.
• Subscreens allow you to embed one screen within another at runtime. You can include multiple sub-screens on main screen.
• The term subscreen applies both to the screen that you embed, and the area on the main screen in which you place it. This tutorial is about subscreen areas. The actual screens created through SE51 transaction, are called subscreen screens if defined in screen attributes.
• When you use a subscreen, the flow logic of the embedded screen is also embedded in the flow logic of the main screen.Hence, Using subscreens on screens is like using includes in ABAP programs.
