Calling FM in methods

Former Member — Mon, 01 Oct 2007 12:42:41 GMT

Hi Friends,

I am trying to call a GUI_download function module inside a method.

But after executing it is throwing an error message stating that FM does not exists or exceptions raised.

Kindly suggest..

Regards,

Chaitanya

Hi,

Uncomment the EXCEPTIONS part & handle the sy-subrc.

Check in debug mode, which exception is raised.

You might not have some authorization to download on a specific directory.

Best regards,

Hi Prashant,

Thanks for the inputs....

the exceptions have been taken care but the problem is that the FM itself is not getting executed.

So how to debug now???

As soon as it reaches to the calling point it comes out saying that the FM does not exists.

Please advice...

Regards,

Chaitanya.

Hi Kumar,

It seems you are on 4.6B or lower version. Use WS_DOWNLOAD instead of GUI_DOWNLOAD.

Hi,

Don't call the FM inside the method instead call static method GUI_DOWNLOAD of global class CL_GUI_FRONTEND_SERVICES. You can call this directly without instantiating the class.

    call method cl_gui_frontend_services=>gui_download
      exporting
        filename                = ldf_fullpath
        filetype                = 'ASC'
      changing
        data_tab                = gt_outtab
      exceptions
        file_write_error        = 1
        no_batch                = 2
        gui_refuse_filetransfer = 3
        invalid_type            = 4
        no_authority            = 5
        unknown_error           = 6
        header_not_allowed      = 7
        separator_not_allowed   = 8
        filesize_not_allowed    = 9
        header_too_long         = 10
        dp_error_create         = 11
        dp_error_send           = 12
        dp_error_write          = 13
        unknown_dp_error        = 14
        access_denied           = 15
        dp_out_of_memory        = 16
        disk_full               = 17
        dp_timeout              = 18
        file_not_found          = 19
        dataprovider_exception  = 20
        control_flush_error     = 21
        not_supported_by_gui    = 22
        error_no_gui            = 23
        others                  = 24.

  if sy-subrc is not initial.
* handle exceptions here...e.g. RAISE EXCEPTION xxx
  endif.

Don't forget to reward points.

Cheers,

Sougata.

Hi Kumar,

What is the value of sy-subrc after the method <i>cl_gui_frontend_services=>gui_download</i> is called?

Cheers,

Sougata.
