Install the Sabrix connection for SAP

The integration for SAP can be installed on any server environment that supports Java 1.5 or greater.
For the best network performance, it's best to install it on either the tax engine server(s) or the SAP ECC server(s). Network traffic between SAP and the integration can't be compressed whereas traffic between the integration and the tax engine can be compressed.
If you choose to compress the data between the integration and the tax engine, the best place to install the integration would be on SAP ECC server(s).
