How to Integrate CPQ-SAP and handle complex pricing

Hi,

We have a requirement to integrate oracle CPQ with SAP. We are planning to use OIC as middleware. Business wants to store pricing in SAP only. They have a lot of multiple complex pricing conditions.

We like to understand how to integrate the CPQ with SAP using OIC. Secondly, how to handle the complex pricing structure where SAP is a master. Also, will there be any performance impact if SAP store the price.
