Files in application server

I had to download some data into application server.The data was taken from F110 i.e automatic payment transaction and had to be saved in XML format.From that the file was created and it should be saved in the application server i.e AL11.In AL11 the filename had to be generated dynamically.


So I created a function module in which I used the concatenate statement and joined all the data which was coming inside the function module.After that I saved it into a file variable.That I passes to the function module FILE_GET_NAME.This function module is mainly used for converting the logical filename into physical filename and path.For this configuration of the filename was done in transaction FILE.Here the assignment to a physical path was given in format /var//.The syntax group was UNIX.We can give the other platforms it supports.
Basically the difference in logical filename and physical filename is that logical filename is platform independent and physical filename taked the operating system into account and the platform like UNIX,WINDOWS etc.
The value in the filename will be generated dynamically.
