Hi suresh,
Yo cannot declare select-options directly in module pool. First you need to declare a subscreen area in layout and then in the top include you can declare the selection screen like:
SELECTION-SCREEN BEGIN OF SCREEN 100 AS SUBSCREEN.
select-options s_carrid FOR wa_spfli-carrid NO INTERVALS.
SELECTION-SCREEN END OF SCREEN.
And then call the sub-screen area:
CALL SUBCREEN sub_area INCLUDING <program> <screen>.
With regards,
