Could some one please help me out and with this? Thank you for your input.

I think that you should simply pass the FT_ITAB to the method call. No reason to put it in a local variable before passing.

  call method cl_gui_frontend_services=>gui_upload
            exporting
              filename                     = lw_filename
              filetype                       = lw_filetype
            changing
              data_tab                     = ft_itab         "<--- CHange this

Thank you Rich.

When I comment this line lt_itab = ft_itab.

it doesn't gives me an error but when I try to fun the program it gives me an error. Could you please be specific with your comment on this:

data_tab = ft_itab "<--- CHange this

Thank you

[RichHeilman]

What is the error that you are getting, also please paste the modified code here.

The error I get is

"Type conflict when calling a method."

Error analysis:

An exception occurred that is explained in detail below.

The exception, which is assigned to class 'CX_SY_DYN_CALL_ILLEGAL_TYPE', was

not caught in

procedure "ADA_PC_FILE_IN_ITAB_STELLEN" "(FORM)", nor was it propagated by a

RAISING clause.

Since the caller of the procedure could not have anticipated that the

exception would occur, the current program is terminated.

The reason for the exception is:

Type conflict when calling the method "GUI_UPLOAD" of the class

"CL_GUI_FRONTEND_SERVICES". It was tried

to transfer a non-compatible variable to the formal parameter "DATA_TAB".

This is my new code:

FORM ada_pc_file_in_itab_stellen

TABLES ft_itab

USING value(fw_filename) TYPE c

value(fw_filetype) TYPE c

value(fw_popup) TYPE c

value(fw_ausgabe_art) TYPE c

CHANGING fw_subrc LIKE sy-subrc

fw_lines LIKE w_lines.

CALL METHOD cl_gui_frontend_services=>gui_upload

EXPORTING

filename = lw_filename

filetype = lw_filetype

CHANGING

data_tab = ft_itab

EXCEPTIONS

endform.

Please make sure that you have defined the tables that are being passed via FT_ITAB as internal tables without header lines. Or you can simply call function module GUI_UPLOAD instead of the class/method.

Thanks you all very much. I can't use the function GUI_UPLOAD bc it is non unicode and that's why I am calling the method of the class.

Problem still persist though.

[RichHeilman]

GUI_UPLOAD is unicode compliant, it is actually called directly inside of the cl_gui_frontend_services=>gui_upload method, so in reality, you are using it. The difference between calling it directly and using the class, is that the class enforces that you do not pass an internal table with header line. Post all of your code so we can take a look.

Hello Nadin

Sounds like you have to make the <b>SSM </b>(<i>Standard Schnittstellen Management</i>) Unicode-enabled.

The SSM has been developed by <b>Cirrus Consulting AG</b> for which I have worked until end of July.

In July I have adapted the SSM for Unicode systems since one of Cirrus' customers uses SSM and they have upgraded their systems to ECC 6.0 (Unicode).

You should change your coding as following:

Hello Uwe,

thank you so much. When I uses this code

DATA: lt_data        TYPE standard table.

I have the error: Any table expected not standard table.

when I change it to

DATA: lt_data        TYPE any table

.

I get the message "you can not use generic types for fields. The table Types ANY and INDEX are generic.

Could you help on this Uwe? Thank you.

You may need to specify the table to exclude any header line:

          CHANGING
            data_tab                     = ft_itab[]   "<<<< table body only

Andrew

[RichHeilman]

I think Andrew has it, you can use the [] to specify only the body of the internal table, but it would be a good programming practice to start getting used to defining your internal tables without header lines, because they can not be used within the OO context.
