Working with Files on the Presentation Server 

To work with files on the presentation server, you use special function modules. Internal tables serve as an interface between your programs and the function modules. You can use these function modules to:

Write Data to the Presentation Server with a User Dialog

Write Data to the Presentation Server without a User Dialog

Read Data from the Presentation Server with a User Dialog

Read Data from the Presentation Server without a User Dialog

Check Files on the Presentation Server

The physical names of the files depend on the operating system of the presentation server. You can, however, make your ABAP programs platform-independent by using logical filenames. For further information, refer to Using Platform-Independent Filenames.
