Finding function modules

Former Member — Sun, 06 May 2007 12:44:22 GMT

Hello Frnds,

I have a query regarding Funtion modules. Actually i m working in newer version so i want to know the replacement for the older version.

Suppose earlier for uploading flat file data we used "ws_upload". But now in newer version we are using "GUI upload". So can anyone help me that how to find the new replacement function modules for the older ones.

i.e in SAP.

thanking u all.

regards,

karan

<b>Refer the following code:</b>

*&---------------------------------------------------------------------*
*&      Form  upload_file
*&---------------------------------------------------------------------*
*       text
*----------------------------------------------------------------------*

FORM upload_file  USING    p_filename TYPE any
             CHANGING p_local_table TYPE t_local_table.

* To get the input data from desktop file


    DATA:  l_file TYPE string.
    CLEAR: l_file,
           p_local_table.

    l_file = p_filename.

    CALL FUNCTION 'GUI_UPLOAD'
      EXPORTING
        filename                = l_file
        filetype                = 'ASC'
      TABLES
        data_tab                = p_local_table
      EXCEPTIONS
        file_open_error         = 1
        file_read_error         = 2
        no_batch                = 3
        gui_refuse_filetransfer = 4
        invalid_type            = 5
        no_authority            = 6
        unknown_error           = 7
        bad_data_format         = 8
        header_not_allowed      = 9
        separator_not_allowed   = 10
        header_too_long         = 11
        unknown_dp_error        = 12
        access_denied           = 13
        dp_out_of_memory        = 14
        disk_full               = 15
        dp_timeout              = 16
        OTHERS                  = 17.
    IF sy-subrc <> 0.
      MESSAGE e002 WITH l_file.
    ENDIF.
  
ENDFORM.                    " upload_file

Here l_file is the desktop file path and p_local_table is the internal table where the data is to be uploaded from the local file.

Hi!

The replacements are sometimes documented by SAP.

If they are not, just post here your EXACT wish, which FM do you want to upgrade, and someone will surely tell you within a few minutes.

There is no specific way. You can 'Function Module documentation' in SE37. You can get some help.Ex: For 'WS_UPLOAD' , 'Function Module documentation' clearly says that :

<b>FU WS_UPLOAD

____________________________________________________

Text

OBSOLETE: Transfer Presentation Server File to Internal Table

Uploads a file from the presentation server into an internal table.

Obsolete. Use class CL_GUI_FRONTEND_SERVICES.</b>

Now, If you dont find a FM in newer version, You can search a FM which does the similar task in the newer version. Such as in the newer version for uploading flat file :

1. Open SE37

2. Write 'UPLOAD' in the Functional module name

3. Then press F4

4. From the help you can find a appopriate FM

In some 'Function Module documentation' also, you will find a SAP recomendation for replacement of a older FM.
