SAP Customer Checkout integration with SAP CAR

Hi All,

We have few queries on SAP Customer Checkout integration with SAP CAR.

In general, SAP PO will receive all the sale transactions in form of XML file from front end POS Store center (Other POS software vendors) via SFTP and transforms data to SAP CAR system.

How this process will work if we are implementing SAP CCO and integrating with SAP CAR ?

Thanks
