When i click the button i wanna change this field's no-out property

[Former Member]

DATA :   gt_fcat    TYPE lvc_t_fcat         WITH HEADER LINE       ,

             gs_fcat    TYPE lvc_s_fcat                .

*****

              clear gs_fcat.

              gs_fcat-col_pos   = 16.

             gs_fcat-fieldname = BETRG.

             gs_fcat-tabname   = GT_ITAB .

             gs_fcat-reptext  = 'Pays'.

             gs_fcat-NO_OUT    = 'X '.

     APPEND gs_fcat TO gt_fcat.

******

WHEN '&BT1'.

LOOP AT GT_FCAT.

IF  gt_fcat-fieldname = 'BETRG'.

   refresh gt_fcat[].

      CLEAR gs_fcat.

      gs_fcat-NO_OUT    = ' '.

      APPEND gs_fcat TO gt_fcat.

      MODIFY GT_FCAT[].

ENDIF.

ENDLOOP.

Problem is when i click button betrg field doesn't seem still.

i never was able to do this with reuse alv

but you can try this solution

you need to use ALV OO

with the set_frontend_fieldcatalog method set the new field catalog

CALL METHOD go_alv->set_frontend_fieldcatalog

     exporting

          it_fieldcatalog = t_filedcat[].

and then refresh the alv.

Good luck
