The SAP front-end software can either RUN on the similar computer or on different computers provided for that purpose. User terminal input is established by the SAP terminal program SAP GUI, converted to SAP proprietary format and sent to the SAP dispatcher. The dispatcher organizes the information exchange between the SAP GUI's and the work processes. The dispatcher first places the processing REQUEST in request QUEUES, which it then processes. The dispatcher dispatches the requests one after another, to the accessible work process. The actual processing takes place in the work process. When processing is done, the PRODUCT of a work process is returned via the dispatcher to the SAP GUI. The SAP GUI read the received data and generates the output screen for the user.
