Call function GUI_DOWNLOAD

Former Member — Thu, 06 Apr 2006 11:56:43 GMT

hi,

I use the fm 'GUI_DOWNLOAD' to download some information in a file. Now I call the fm in my program:

    CALL METHOD CL_GUI_FRONTEND_SERVICES=>GUI_DOWNLOAD
      EXPORTING
*      BIN_FILESIZE            =
       FILENAME                =  p_file
       FILETYPE                = 'ASC'

*    IMPORTING
*      FILELENGTH              =
       CHANGING
       DATA_TAB                = tab[]

As importing-parameter I use following tab:

DATA: BEGIN OF st,
       line(1000),
      END OF st.

DATA: tab LIKE standard TABLE OF st WITH HEADER LINE.

Now if I call the fm like:


.....
DATA_TAB             = tab

I get an error. If I call it with "DATA_TAB = tab[]" -> there is no error --> why???

Thanks

Hi,

The size of the field string used in Data_tab is 255 characters and you have declared the tab as 1000 characters. That is the reason for the problem.

because <b>tab</b> means header line not the internal table.

<b>tab[]</b> means internal table.you need to pass the internal table not the header line..

Markus,

That is because you have declared the table with header line. So, just tab means the header line and is nothing a single record. tab[] means the body of the table and that is what is expected in the parameter.

when you r passing the parameter as tab the table is not inatializing properly so that you r getting the error but when you are giving as tab[] the table is getting initialized and value is now store in the fields of the table so it is not giving the error.

I hope this will help you to solve your problem.

Nonsens. Regarding ERP 2005/2004 and Unicode you have to use Methods of the class cl_gui_frontend_services.
