Instrument drop down shows Logic twice

Question

Attached is screen shot of the instrument channel drop down choices . Notice how Logic appears twice, once normal and then under the AU Instruments.
Just wondering what is at play here. thanks, Kendall

Answer 1

Ensure your code follows below logic
PARAMETERS: pa_it TYPE t582s-infty AS LISTBOX VISIBLE LENGTH 40 MODIF ID 2md.
TYPES: BEGIN OF t_infty,
        infty TYPE t582s-infty,
        itext TYPE char40,
       END OF t_infty.
DATA: it_infty TYPE STANDARD TABLE OF t_infty WITH HEADER LINE.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR pa_it.
    REFRESH it_infty.
    SELECT * FROM t582s WHERE sprsl = sy-langu.
      MOVE-CORRESPONDING t582s TO it_infty.
      it_infty-itext = t582s-itext.
      CONCATENATE it_infty-infty t582s-itext INTO it_infty-itext SEPARATED BY ' - '.
      APPEND it_infty.
    ENDSELECT.
    PERFORM dropdown_list_values_create TABLES it_infty USING  'INFTY'.
FORM dropdown_list_values_create  TABLES f_tab
                                  USING retfield TYPE dfies-fieldname.
  "display internal table as a dropdown list,
  "return field 'INFTY' when the event is trigerred
  CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
    EXPORTING
      retfield        = retfield
      value_org       = 'S'
    TABLES
      value_tab       = f_tab
    EXCEPTIONS
      parameter_error = 1
      no_values_found = 2
      OTHERS          = 3.
  IF sy-subrc <> 0.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
            WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  ENDIF.
ENDFORM.                    "dropdown_list_values_create
