Modify fieldcat

[Former Member]

Guys , Im creating a ALV using the following code ,

CALL METHOD grid1->set_table_for_first_display
      EXPORTING
        i_structure_name = 'CAUFVD'
        is_variant       = gs_variant
        is_layout        = gs_layout
        i_save           = x_save
      CHANGING
        it_outtab        = ti_saida[].

However I want to change the text of the fields ( columns ) , they come assigned for texts of CAUFVD , a friend told me that maybe is neccesary to change the fieldcat , how is that?

Try thsi way

  v_structure = 'CAUFVD'.

  call function 'LVC_FIELDCATALOG_MERGE'
    exporting
      i_structure_name       = v_structure
      i_client_never_display = c_x
    changing
      ct_fieldcat            = i_fieldcat[].

  loop at i_fieldcat where fieldname eq 'PROD' .
 
    move : text-008 to i_fieldcat-scrtext_m,
                                        " Product code
           text-008 to i_fieldcat-reptext,
                                        " Product code
           text-008 to i_fieldcat-coltext.
                                        " Product code
    modify i_fieldcat index sy-tabix.
   endloop.
...
...
...
    call method grid1->set_table_for_first_display
      exporting
        is_layout                     = gs_layout
        is_variant                    = gs_variant
        i_save                        = 'A'
        it_toolbar_excluding          = i_exclude[]
      changing
        it_outtab                     = i_output[]
        it_fieldcatalog               = i_fieldcat[]
      exceptions
        invalid_parameter_combination = 1
        program_error                 = 2
        too_many_lines                = 3
        others                        = 4.

Hi, I did it this way,

 call function 'LVC_FIELDCATALOG_MERGE'
    exporting
      i_structure_name       = 'CAUFVD'
      i_client_never_display = 'X'
    changing
      ct_fieldcat            = fieldcat[].

LOOP AT fieldcat where fieldname eq 'GSTRP' .
        fieldcat-reptext = 'Data solicitação'.
         modify fieldcat index sy-tabix.

   ENDLOOP.

   CALL METHOD grid1->set_table_for_first_display
      EXPORTING
*        i_structure_name = 'CAUFVD'
        is_variant       = gs_variant
        is_layout        = gs_layout
        i_save           = x_save
      CHANGING
        it_outtab        = ti_saida[]
        it_fieldcatalog  = fieldcat[]
      exceptions
        invalid_parameter_combination = 1
        program_error                 = 2
        too_many_lines                = 3
        others                        = 4.

  ENDIF.

but it still shows the old text. any idea please?

Hi,

Try like this...

field-symbols: <lwa_fcat>  type lvc_s_fcat.

call function 'LVC_FIELDCATALOG_MERGE'
      exporting
        i_structure_name       = 'CAUFVD'
      changing
        ct_fieldcat            = fieldcat[]
      exceptions
        inconsistent_interface = 1
        program_error          = 2
        others                 = 3.

loop at fieldcat assigning <lwa_fcat>.
      case <lwa_fcat>-fieldname.
          when 'STATUS'.
          <lwa_fcat>-outputlen = 25.
          <lwa_fcat>-coltext   = 'STATUS'.
      endcase.
    endloop.


CALL METHOD grid1->set_table_for_first_display
      EXPORTING
*        i_structure_name = 'CAUFVD'
        is_variant       = gs_variant
        is_layout        = gs_layout
        i_save           = x_save
      CHANGING
        it_outtab        = ti_saida[]
        it_fieldcatalog  = fieldcat[]
      exceptions
        invalid_parameter_combination = 1
        program_error                 = 2
        too_many_lines                = 3
        others                        = 4.
 
  ENDIF.

Hi,

If you want to change column heading means you have to set field catalog coltext field not reptext field.

Hope you have understand
