Dear All,

Can anyone tell me how to use the function module

DX_FILE_READ? Also, can I use it for downloading a file from application server?

Thanks.

Regards,

Rupesh

DX_FILE_READ is used to read the file from PS or AS ....

if you pass X to the PC in exporting parameter it will pick file from Presentation Server ....

or else ir will search for the file in the server which u specified ....
