In the GUI status of the selection screen set by the system, the application toolbar contains five inactive pushbuttons, to which the function codes FC01 to FC05 are assigned. This statement activates the pushbutton of the function code FC0n, whereby a value between 1 and 5 must be entered for n.

To enable use of the pushbuttons, the statement TABLES must be used to declare an interface work area of the structure SSCRFIELDS from the ABAP Dictionary.

To activate pushbuttons on the selection screen, Please follow the sample program.
