Is it possible to use C1 OnRamp Adapter with SAP EBP Applica

We are receiving the Purchase Order Message in xCBL format from SAP EBP application. Our task is to Map the incoming request into a SAP IDOC(ORDERS05)and send the same to the SAP R/3 system.
Also when the INVOIC02 IDOC is generated we map it to the invoice xCBL and send it back to the SAP EBP system.
At the moment we are looking at manually creating the services to accept the request and to process the response.
Can we use a C1 On Ramp adapter for this purpose?
Please enlighten me on the issue.

Thank you.
