KPI Connector 
A connector used to run queries against Key Performance Indicator (KPI).
You can have only one active KPI connector. If you want to use multiple KPI data sources where each data source has different dimensions and values, do the following:
Set up the desired number of KPI data sources on the SAP NetWeaver server.
Specify the server on the Data Provider screen in the KPI DataSource field.
Enable the KPI connector with the appropriate.
Disable the other KPI connectors.
The property KPI Instance Name on the Connection tab of the Data Servers screen defines the KPI connector instance that is used.
You must enter an associated KPI data source on the System Properties screen. To do so, on the SAP MII administration screen, choose You use the KPI connector when you create an KPI query. For more information, see KPI Framework Query.
