What does the dispatcher does?
A) The dispatcher distributes the transaction load among various work process, connecting to the presentation level and organizing communication. The processing requests are first saved in request queues and then processed according to 'first in -- first out' rule.
Does Dispatcher process data?
A) No, the data is processed in work process like dialog wp or background wp or update wp etc.. The dispatcher only distributes load between work process. There is no assignment of a work process to single user. The requests which are created by user using SAPGUI is distributed among the work process. Processing user requests sometimes requires data to be read from the database or written to it. For this, every work process is connected directly to the database.
