Runtime Error: GETWA_NOT_ASSIGNED

[walkerist79]

I was trying to select from table SCARR, SPFLI using specific parameters. When something is selected, it should be transferred from internal table to ALV.

Here's my code:

REPORT ABC MESSAGE-ID MSG_TEST.

       END OF i_tab.

       lv_connid TYPE spfli-connid,

SELECT SINGLE CARRID
         FROM SCARR
         INTO @lv_carrid
        WHERE carrid = @p_carrid.

    AND connid = @p_connid.

                      ( fieldname = 'spfli_countryto' seltext_l = 'Country To')

Hi Wane,

Please try below code. It's working. I changed field names in fieldcatelog. You need to pass same field name which you have used in structure.

TABLES: SPFLI,
        SCARR.
*PARAMETER DECLARATION
SELECTION-SCREEN BEGIN OF BLOCK b1.
PARAMETERS: p_carrid TYPE scarr-carrid DEFAULT 'AA',
            p_connid TYPE spfli-connid DEFAULT '0017'.
SELECTION-SCREEN END OF BLOCK b1.
START-OF-SELECTION.
TYPES: BEGIN OF i_tab,
       carrid TYPE spfli-carrid,
       connid TYPE spfli-connid,
       countryfr TYPE spfli-countryfr,
       countryto TYPE spfli-countryto,
       END OF i_tab.
DATA:  lv_carrid TYPE scarr-carrid,
       lv_connid TYPE spfli-connid,
       i_spfli TYPE STANDARD TABLE OF i_tab,
       i_fieldcat TYPE slis_t_fieldcat_alv.
START-OF-SELECTION.
SELECT SINGLE CARRID
         FROM SCARR
         INTO @lv_carrid
        WHERE carrid = @p_carrid.
IF sy-subrc <> 0.
*    MESSAGE E001.
    STOP.
ENDIF.
END-OF-SELECTION.
START-OF-SELECTION.
SELECT CARRID,
       CONNID,
       COUNTRYFR,
       COUNTRYTO
  FROM SPFLI
  INTO TABLE @i_spfli
  WHERE carrid = @p_carrid
    AND connid = @p_connid.
IF sy-subrc <> 0.
*    MESSAGE I001.
    STOP.
ENDIF.
*PASSING OF SELECTED VALUES INTO ALV
i_fieldcat = VALUE #( ( fieldname = 'CARRID'        seltext_l = 'Airline Code')
                      ( fieldname = 'CONNID'        seltext_l = 'Flight Connection')
                      ( fieldname = 'COUNTRYFR' seltext_l = 'Country From' )
                      ( fieldname = 'COUNTRYTO' seltext_l = 'Country To')
                    ).
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
    EXPORTING
       I_INTERFACE_CHECK                 = 'X'
        it_fieldcat = i_fieldcat
    TABLES
        t_outtab    = i_spfli
    EXCEPTIONS
        program_error = 1
        others        = 2.
IF sy-subrc <> 0.
    MESSAGE |An Error Occured!| TYPE 'E'.
ENDIF.
END-OF-SELECTION.

Hi Wane,

In above code I have added I_INTERFACE_CHECK = 'X' in REUSE_AV_GRID_DISPLAY FM to check the error you can comment it once code is working. Also I comment message also in my code you can uncomment it.

Don't use REUSE_ALV_GRID_DISPLAY. It's error prone and is deprecated.

Instead, use CL_SALV_TABLE.
