Overview  

Application data must often be stored outside the database in files. Files will be stored in different directories depending on the operating system, and the file and path names must satisfy different syntax requirements. Many SAP applications call the function module FILE_GET_NAME, which gets the platform-specific file name and path for a logical file name, when saving files.

This function module and logical file names standardize file names and paths in application programs, independently of the hardware and software platforms.

Logical file names and paths must be defined in the system. These definitions can be maintained the IMG section Application Server ® System Administration ® Cross-PlatformFile Names, with the transactions FILE and SF01. The definitions used by SAP applications are delivered with the system, and adjusted during implementation. Which applications use which logical file names is in the application documentation. You can add new definitions.
