An SAP message server can be used for load distribution and communication between individual application servers in an SAP BW system. When you create an SAP BW connection in Spotfire, you must specify whether you will connect directly to an application server, or if you want to connect via a message server.

To connect to an SAP BW data source via a message server, select Connection type > Group/Server selection in the SAP BW connection dialog. Different information is required to create a connection to an SAP BW data source via a message server, compared to when you connect directly to the application server.
