Does the connector need PI?

In order to install the SAP Connector or to make customizations, it is not required to have knowledge of SAP PI. The connector is working both with and without SAP PI. The ABAP stack already has the mapping to PI, so it’s an option whether you required the use of PI or not.

When extra data entities are created as additional requirements, the SAP engineer should have some basic understanding of SAP PI, because (s)he needs to map the PI to the new end point in the SOA Manager.
