Logon load balancing is used to distribute SAP users dynamically across application server instances. You can maximize the efficiency of every defined workgroup by setting up various logon workgroups that consist of one or more application instances,.

You can assign one or more application servers to specific workgroups or applications. When the users log on to the system, they are automatically logged on to the server that currently has the best performance statistics and/or the lowest number of logged on users.

Workgroups are configured and maintained centrally from within the SAP System. Each application server group is assigned maximum threshold values for response time and the number of users that can log on to a specific group server. Especially important workgroups with time-critical transactions can be assigned to application servers with improved response time behavior. Setting up workgroups makes it easier to predict the behavior of each server, thereby enabling you to set up each server according to the working applications.

To log on to an SAP System, the user only needs to know the name of the SAP System and the logon group. Host name and system numbers are no longer needed once you have logged on.
