You want to use the RS_SET_SELSCREEN_STATUS function module to set a GUI status (which does not come from the program to which the screen itself belongs, but from another report) for a selection screen. This status was created as a copy of the default status for selection screens. If the status uses the function keys that can be activated with the SELECTION-SCREEN FUNCTION-KEY ABAP statement, then the dynamic texts defined in the SSCRFIELDS structure may not be displayed.
Importing a kernel patch.
If the status is in a function group and if the RS_SET_SELSCREEN_STATUS function module is to used to set this status for a selection screen, you must set the fields from SSCRFIELDS in the function group yourself.
