Hi
i need to read a comma separated text file.
i am using
cl_gui_frontend_services=>gui_upload
but i am not able to get what table type i should use in the importing parameter.i am getting an error. itab is not type compatible with importing parameter.
right now i am using the following code.

types: begin of ita,
rec(1000) type c,
end of ita.
data: itab type standard table of ita with header line.

end of itab22.
data: file type string.
data: itab2 type standard table of itab22 with header line.
file = 'C:\test.txt'.
call method cl_gui_frontend_services=>gui_upload
exporting
filename = file
filetype = 'ASC'
has_field_separator = 'X'
changing
data_tab = itab

others = 17
if sy-subrc <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

split itab-rec at ',' into itab22-matnr.
itab22-werks.
itab22-quant.
append itab22.
endloop.

Hi...
Check this in your code:
data: itab2 type standard table of itab22 with header line.
Internal Tables with header line cannot be passed to a method.
So declare like this (without header line).
data: itab2 type standard table of itab22 .
Then it works.
