update field catalog alv grid

[former_member579227]

Hallo,

I have to update my fieldcatalog on a ALV GRID in screen 200.

From screen 100 I click a button and I call screen 200.

Here, the first time I creat the filedcatalog and I use the metod:

CALL METHOD go_grid_inv->set_table_for_first_display

Then I click BACK and return to screen 100.

Now, I click th button and call screen 200 again. Now I use the method:

CALL METHOD go_grid_inv->refresh_table_display.

I don't know how I can change my fieldcatalog (deleting same columns).

help.

in the pbo of every screen u can use the fn module to display and pass field cat separately.

so whenever u use call screen , it will go to the exact screen.

if my answer is not related, pls explain ur question some what clearly

Sorry but I didn't understand:

this is the code:

MODULE status_0200 OUTPUT.

SET PF-STATUS 'GS_200'.

PERFORM modify_screen.

IF go_custom_container_inv IS INITIAL.

CREATE OBJECT go_custom_container_inv

EXPORTING container_name = 'CC_ALV_INVENTARIO'.

CREATE OBJECT go_grid_inv

EXPORTING

i_parent = go_custom_container_inv.

PERFORM build_fieldcatalog_i

CHANGING gt_fieldcat.

gs_layout-info_fname = 'COLOR_LINE'.

gs_layout-excp_fname = 'TRAFFIC_LIGHT'.

CALL METHOD go_grid_inv->set_table_for_first_display

EXPORTING

i_structure_name = 'zcat_inv_ctrl'

is_layout = gs_layout

CHANGING

it_fieldcatalog = gt_fieldcat

it_outtab = it_record.

ELSE.

CALL METHOD go_grid_inv->refresh_table_display.

ENDIF.

ENDMODULE. " STATUS_0200 OUTPUT

when the go_custom_container_inv is not INITIAL, how I can change my fielcatalog?

[hymavathi_oruganti]

if go_custom_container is not initial means, already there is some grid in that.

1. make sure to refresh custom container after display is complered.

refresh go_custom_container

2. again if u want to call the grid of screen 100, no need to delete fieldcat.

in PBO of screen 100 call anothet set_table_for_first_display.

so whenever u sau call screen 100. it automatically displays.

I've used

CALL METHOD go_grid_inv->set_frontend_fieldcatalog

EXPORTING it_fieldcatalog = gt_fieldcat.

before

CALL METHOD go_grid_inv->refresh_table_display.

..and all work well.

thx

I had to set the layout again as well.  As the table refresh lost the layout settings after calling the set_frontend_fieldcatalog method.

  CALL METHOD go_grid_inv->set_frontend_layout

      EXPORTING

        is_layout = gt_layout.

Works great now thanks!
