hi,

in ur gui download function module pass internal table body not work area.

for ex: if internal table is with out header line u have to pass body of taht internal table and if internal table is with header line then give internal table name.

CALL METHOD cl_gui_frontend_services=>gui_upload

EXPORTING

FILENAME = 'c:\praveen.txt'

FILETYPE = 'asc'

CHANGING

data_tab = itab[]. ///////// when internal table is with out header line.

and data_tab = itab //// when internal table is with header line.

if helpful reward some points.

Hello Praveen,

You need to change internal table declaration,

see the below link:

Thanks

Try to use like this the internal table declaration

REPORT ZSAMPLEBDC .

tables :kna1.

types : begin of ty_itab,
          kunnr like kna1-kunnr,
          name1 like kna1-name1,
          land1 like kna1-land1,
        end of ty_itab.

data : itab type table of ty_itab, " Internal table
       ltab type ty_itab. " Work Area

CALL METHOD cl_gui_frontend_services=>gui_upload
  EXPORTING
    FILENAME = 'c:praveen.txt'
    FILETYPE = 'asc'
  CHANGING
    data_tab = itab.

loop at itab.
  write :/tab.
endloop.

Since that you are using classes, you can not use Header Line.
