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.
