Hi Mark,

Try along this line:

data it_scarr type standard of scarr.

SELECT Carrid carrname

FROM scarr

INTO CORRESPONDING FIELDS OF TABLE it_scarr.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

retfield = 'carrid'

value_org = 'S'

TABLES

value_tab = it_scarr

EXCEPTIONS

parameter_error = 1

no_values_found = 2

OTHERS = 3.

IF sy-subrc <> 0.

(MESSAGE 'Choose from dropdown list ').

ENDIF.
