Click Pattern, click the radiobutton for AABAP Objects patterns, click green check icon. You will get a dialog, type the name of the instance, the class, and the method, and click the green check.

If you are calling a static method, then you don't have to fill in the instance field.

Hi,

You can call a method by clicking the Patterns button as mentioned by one the Developers above. In that choose the ABAP Objects radiobutton, Then a screen will be displayed with many options like call method, constructor..etc.

Not sure that I understand your question here, but I'll try to help. Usually with that class, CL_GUI_FRONTEND_SERVICES, I do not bother creating a instance or object of the class. I usually just call the static method of the class.

Like so.....



call method cl_gui_frontend_services=>file_save_dialog
*  EXPORTING
*    WINDOW_TITLE      =
*    DEFAULT_EXTENSION =
*    DEFAULT_FILE_NAME =
*    FILE_FILTER       =
*    INITIAL_DIRECTORY =
  changing
    filename          =
    path              =
    fullpath          =
*    USER_ACTION       =
*  EXCEPTIONS
*    CNTL_ERROR        = 1
*    ERROR_NO_GUI      = 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.

In the ABAP objects pattern, I filled in the CLASS name as CL_GUI_FRONTEND_SERVICES, then did a drop down on the method field, selected the method and clicked green check.

There are other ways of doing it, but, what I've done in the past is declared my "output" itab as all character fields....

example


data: begin of itab occurs 0,
      field1(50) type c,
      field2(50) type c,
      field3(50) type c,
      end of itab.

Then when writing to the output itab, write out the column headings in the first row of the itab.


clear itab.
itab-field1 = 'Material'.
itab-field2 = 'Plant'.
itab-field3 = 'Description'.
append itab.

Then fill in the rest of the itab with your data.


loop at x.
clear itab.
itab-field1 = x-matnr.
itab-field2 = x-werks.
itab-field3 = x-matkx.
append itab.

endloop.

Now use the GUI_DOWNLOAD.

Here is another example of writing headings to excel, this one actually opens up excel at the same time. Not sure that this will work for you.



report zrich_0002 .

data: begin of itab occurs 0,
      field1(10) type c,
      field2(10) type c,
      field3(10) type c,
      end of itab.

data: begin of itabfn occurs 0,
      fieldname(10) type c,
      end of itabfn.

* Set column headings.
itabfn-fieldname = 'Field 1'.
append itabfn.
itabfn-fieldname = 'Field 2'.
append itabfn.
itabfn-fieldname = 'Field 3'.
append itabfn.

* set data
do 10 times.
  clear itab.
  itab-field1 = 'field1'.
  itab-field2 = 'field2'.
  itab-field3 = 'field3'.
  append itab.
enddo.

call function 'EXCEL_OLE_STANDARD_DAT'
  exporting
    file_name                       = 'C:abapstext'
*   CREATE_PIVOT                    = 0
*   DATA_SHEET_NAME                 = ' '
*   PIVOT_SHEET_NAME                = ' '
*   PASSWORD                        = ' '
*   PASSWORD_OPTION                 = 0
 tables
*   PIVOT_FIELD_TAB                 =
   data_tab                        = itab
   fieldnames                      = itabfn
* EXCEPTIONS
*   FILE_NOT_EXIST                  = 1
*   FILENAME_EXPECTED               = 2
*   COMMUNICATION_ERROR             = 3
*   OLE_OBJECT_METHOD_ERROR         = 4
*   OLE_OBJECT_PROPERTY_ERROR       = 5
*   INVALID_FILENAME                = 6
*   INVALID_PIVOT_FIELDS            = 7
*   DOWNLOAD_PROBLEM                = 8
*   OTHERS                          = 9
          .
if sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
endif.
