Ariba integration with CIG - PO instead of Cloud Connector

Hi guys,

We are going to implement Ariba in our compagny, using Cloud Integration Gateway.

The documentation recommand to use Cloud Connector to connect CIG to our on premise ERP.

The documentation also mention that PI/PO can be used (SAP provides a software component for that), but I don't really understand what would be its role in this integration.

We have PI/PO in our landscape for a lot of integrations and we are interested in keeping using it.

May PO replace completely the Cloud Connector? Would it be a valid scenario soported by SAP?

Thank you

Best regards

Fred
