Exporting a Report to an External File 
Use
You can export reports to an external file on the presentation server or to a file on the application server.
Features
The application server is the computer that is running the SAP R/3 System (for example, a UNIX-based workstation assigned to your department).
The presentation server is the computer that is running your R/3 interface (for example, a PC linked to an R/3 application server).
For more information on these two alternative functions, see
Exporting a Report to a Presentation Server and Exporting a Report to an Application Server.
