Error showing exception column

[Former Member]

Hi,

I get the following error message trying to generate an exeption column:

Field "USAGE" is unknown.

I have the following sample code:

**********************************************************************************

REPORT zdktesticon.

TYPE-POOLS: icon.

TYPES: BEGIN OF t_sflight.

INCLUDE STRUCTURE sflight.

TYPES: seatsfree TYPE sflight-seatsocc,

• exception

usage TYPE n,

END OF t_sflight.

• Internal table

DATA: it_sflight TYPE TABLE OF t_sflight.

• Workarea for data fetch

DATA: wa_sflight LIKE LINE OF it_sflight.

• Reference for ALV instance

DATA: gr_alv TYPE REF TO cl_salv_table.

DATA: lr_columns

TYPE REF TO cl_salv_columns_table.

DATA: lr_column

TYPE REF TO cl_salv_column_table.

START-OF-SELECTION.

• retrieve data into internal table

SELECT * FROM sflight

INTO CORRESPONDING FIELDS OF TABLE it_sflight.

• fill additional data fields

LOOP AT it_sflight INTO wa_sflight.

• seats free

wa_sflight-seatsfree = wa_sflight-seatsmax + wa_sflight-seatsmax_b

+ wa_sflight-seatsmax_f

- wa_sflight-seatsocc - wa_sflight-seatsocc_b

- wa_sflight-seatsocc_f.

• usage (exception light)

IF wa_sflight-seatsfree = 0.

wa_sflight-usage = '1'.

ELSEIF wa_sflight-seatsfree <= 20.

wa_sflight-usage = '2'.

ELSE.

wa_sflight-usage = '3'.

ENDIF.

MODIFY it_sflight

FROM wa_sflight

TRANSPORTING

seatsfree

usage.

ENDLOOP.

• TRY.

CALL METHOD cl_salv_table=>factory

IMPORTING

r_salv_table = gr_alv

CHANGING

t_table = it_sflight.

• CATCH cx_salv_msg.

*

*

• ENDTRY.

• get columns object

lr_columns = gr_alv->get_columns( ).

lr_columns->set_exception_column(

value = ’usage’

• GROUP = SPACE

• CONDENSED = IF_SALV_C_BOOL_SAP=>FALSE

).

END-OF-SELECTION.

What am I missing?

Hi,

Declare one data value A type lvc_fname value 'USAGE'.

and pass to the method.
