The SAP system includes functions that allow users to work noninteractively, or offline. These functions are handled by the background processing system.
Users normally work interactively with the SAP system. Interactively means they are working online, they input data into the application screens, and the system responds. The interactive service is provided to the users through the dialog work processes.
There is, however, the option of working noninteractively, or offline. Noninteractively means that instead of executing programs and waiting for an answer, users can submit those programs for execution at a more convenient, planned time. This type of work is performed by the background work processes.
