Seles quote follow up document integration with ERP

Hello Experts,

I am trying to set up transactional integration between SAP C4C and SAP ERP, I have an issue, when I request follow-up document from c4c request is sent to sap CPI but can not reach SAP ERP. I am adding a screenshot from Iflow. Could you tell me where can I Find/Configure the endpoint in SAP ERP to receive CPI inbound Idocs ?

Best Regards,

Sandro.
