Hai

Vijayaalakshmi,

This is about dispacther in the Application server.

Dispatcher:

-> The dispatcher is the link between the work processes and the users logged onto the ABAP application server.

-> Its task is to receive requests for dialog steps from the SAP GUI and direct them to a free work process.

-> In the same way, it directs screen output resulting from the dialog step back to the appropriate user.

Dispacher is responsible for receiving requests from users in the presentation server and send output to the users after complete the process by allocating user requests to availble work process.

if useful , reward points.

Thank you

--The central process in the R/3 application layer is the dispatcher. Together with the operating system,the dispatcher controls the resources for the R/3 applications. The main tasks of the dispatcherinclude distributing transaction load to the work processes, connecting to the presentation layer, andorganizing communication.

--User screen input is received by the SAP presentation program SAP GUI, converted into its ownformat, and then sent to the dispatcher. The processing requests are then saved by the dispatcher inrequest queues and processed according to “first in / first out”.

-- The dispatcher distributes (dispatches) the requests one after the other to the available work processes. Data is actually processed in the work process. The user that sent therequest through theSAP GUI is usually not assigned the same work process, because there is no fixed assignment of

work processes to users.

--Once the data has been processed, the processing result from the work process is sent through the dispatcher back to the SAP GUI. The SAP GUI interprets this data and generates the output screen for the user with the help of the operating system on the frontend computer.

-- During initialization of the R/3 System, the dispatcher executes the following actions, among others: it reads the system profile parameters, starts work processes, and logs onto the message server .

Hope its useful..
