Hi,

In ABAP, there is a range of statements for processing data that is stored in sequential files on the application server instead of the database.

· OPEN DATASET opens a file for a particular type of access and storage.

· TRANSFER transfers the contents of a data object to a file.

· READ DATASET transfers data from a file to a data object.

· GET DATASET using the addition POSITION the current position of the file pointer in a file is ascertained. Using the addition ATTRIBUTES further characteristics of the file are obtained.

· SET DATASET using the addition POSITION the position of the file pointer is specified. Using the addition ATTRIBUTES further characteristics of the file can be specified.

· TRUNCATE DATASET sets the end of a file to a specified value, thereby changing the size of the file.

· CLOSE DATASET closes a file.

· DELETE DATASET deletes a file.

Here is the Example program

code is base on uploading a simple txt file.

Hi,

data : begin of l_fname occurs 30,

name(300) type c,

end of l_fname,

begin ofi_dline occurs 0 ,

line(300) type c,

end of l_dline,

i_tab value '|',

l_fname1 type string.

now concatenate all the output fields into l_fname in the o/p format.

concatenate f1 f2 f3 into l_fname separated by i_tab.

append l_fname.

loop at ur final table.

now concatenate all the values into that i_dline separated by i_tab.

append i_dline.

endloop.

Now move the entered file path to l_fname1.

OPEN DATASET l_fname FOR OUTPUT IN LEGACY TEXT MODE.

IF sy-subrc <>0.

"error msg ,if fails to open the file ".

endif.

TRANSFER l_fname to l_fname1.

LOOP AT i_dline.

TRANSFER i_dline-line to l_fname1.

clear i_dline.

if sy-subrc <> 0.

msg download comeplete.

else

download fail.

endif.

CLOSE DATASET l_fname1.

If it helps dont forget REWARD.
