Hi @hervianzhou ,

I'll check it on my installation and I'll come back to you.

I have just quickly checked and seems this setting is applied. Just wondering if you have REF_TABLE and REF_FIELD fields in your field-catalog. Sometimes they mess up things

Hi @fidley ..

i just check the fieldcat before using falv->display.. REF_TABLE and REF_FIELD is blank... both quantity and currency field...

this is all the type i'm declared

      kostl  TYPE coep-kostl,
      lstar  TYPE coep-lstar,
      wtgbtr TYPE coep-wtgbtr,
      twaer  TYPE coep-twaer,
      mbgbtr TYPE coep-mbgbtr,
      meinb  TYPE coep-meinb.

I've played a little bit and I know how to make it work, but I don't know why it doesn't work from scratch....

I've compared the fieldcat of the demo program (which was giving me exactly the same results)

REPORT zdemo_falv24.

TYPES: BEGIN OF t_output,
         price    TYPE sflight-price,
         currency TYPE sflight-currency,
       END OF t_output.

DATA: output TYPE STANDARD TABLE OF t_output.

SELECT price, currency UP TO 10000 ROWS
      INTO CORRESPONDING FIELDS OF TABLE @output
      FROM sflight.

data(falv) = zcl_falv=>create(
               CHANGING
                 ct_table          = output
             ).

falv->column( 'PRICE'  )->set_cfieldname( 'CURRENCY' ).

falv->display( ).

With demo fcat of program from ALV grid in nutshell, where it is working correctly

report zdemo_ain_cl09.
include zdemo_ain_include_screen.

initialization.

select * up to 10000 rows from sflight into table @data(flights).

data(grid) = new cl_gui_alv_grid(
                  i_parent = new cl_gui_custom_container( container_name = 'CC' )
                                 ).
data(fcat) = value lvc_t_fcat(
                               ( fieldname = 'CARRID'  )
                               ( fieldname = 'CONNID' )
                               ( fieldname = 'PRICE' cfieldname = 'CURRENCY' )
                               ( fieldname = 'CURRENCY' )
                             ).

grid->set_table_for_first_display(
  changing
    it_fieldcatalog               = fcat
    it_outtab                     = flights
  exceptions
    invalid_parameter_combination = 1
    program_error                 = 2
    too_many_lines                = 3
    others                        = 4
).
if sy-subrc eq 0.
  call screen 0100.
endif.

And the difference was field TECH_FORM.... in case of correct program it was set to 2, in FALV it was 1. I have no idea where this field is set, as where used list is not working for it, but using method SET_TECH_FORM on that column with value 2, helps. Quite strange.

I will also add this in the next commit as automatic switch from 1 to 2 ;)
