Selection Screen as dynpros
Selection screens are special dynpros that can be defined in executable programs, function groups, and module pools. Selection screens are defined in the global declaration section of the mentioned ABAP programs with the statements SELECT-OPTIONS, SELECTION-SCREEN and PARAMETERS without using Screen Painter. The screens of selection screens can contain a subset of the screen elements of general dynpros.
Selection screens lie in the same namespace as the dynpros of the program. Additionally, dynpro number 1000 is reserved for a standard selection screen. Apart from the standard selection screen, standalone selection screens can also be defined. Standalone selection screens can only be defined in function groups and module pools.
Following example illustrate SELECTION SCREENS.
REPORT YUA_SELSCREEN.
