[Former Member]

HI,

im using method: set_table_for_first_display to show my tabel entries in ALV.

call method go_grid2->set_table_for_first_display

exporting

i_structure_name = 'ZSTRUC1'

is_layout = gs_layout

changing

it_outtab = gt_table

exceptions

others = 4.

How can i edit the fieldcat ? I would like to get rid of some fields in the ALV ?

Hi,

Try like this.....

data : lv_tab_name type dd02l-tabname.

  field-symbols: <lwa_fcat>  type lvc_s_fcat.

  clear :lv_tab_name.
    lv_tab_name = '/RAD/NOT_LINKED_TRACKINGINFO'.
    refresh : gt_fcat[].
    call function 'LVC_FIELDCATALOG_MERGE'
      exporting
        i_structure_name       = lv_tab_name
      changing
        ct_fieldcat            = gt_fcat[]
      exceptions
        inconsistent_interface = 1
        program_error          = 2
        others                 = 3.
    if sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
    endif.

    loop at gt_fcat assigning <lwa_fcat>.
      case <lwa_fcat>-fieldname.
        when 'CLAIM_NUMBER'.
          <lwa_fcat>-no_out = 'X'.
          endcase.
    endloop.

 call method gcc_grid_tr->set_table_for_first_display
      exporting
*          i_structure_name              = c_s_dmhdr
        is_variant                    = gs_variant
        i_save                        = 'A'
        is_layout                     = gs_layout
*        it_toolbar_excluding          = gt_excl_fun[]
      changing
        it_outtab                     = gt_not_linked_trackinginfo[]
        it_fieldcatalog               = gt_fcat[]                                     "field catalog
      exceptions
        invalid_parameter_combination = 1
        program_error                 = 2
        too_many_lines                = 3
        others                        = 4.
    if sy-subrc <> 0.
*     MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*                WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
    endif.

Hello

Use FM 'LVC_FIELDCATALOG_MERGE' before call method.

Hello,

Instead of use the structure importing parameter from the method you need to define the field catalog manually and then pass it to the attribute fieldcat from the method.

Take a look on this: [ALV easy reference|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/e8a1d690-0201-0010-b7ad-d9719a415907]There are three ways to define the field catalog (automatically, semi-automatically and manually).

Regards.
