Writing data in to application server

Hi All,

In lsmw I need to test some data.That program will take only application server files.I need to upload one(Tab delimmitted file ) and test.Here I am trying to upload tab delimitted text file to application server.How can I upload tab delimitted file in to application server.

I have taken one itab and uploaded data from presentation server.Now i am trying to put that itab data in to a file at application server along with tab.

Next I am trying to put that data in to application server file.What can I do to store data as it is like tab delemitted text file in presentation server.

I need to store fields to be stored along with tab.

How can I do it?
