Hi Chandan,
Sorry for the late reply. I had some SCN login issues. I am not sure if you are still facing the issue.
In case you are still facing the issue, could you let know if you are using the SAP provided standard 'SAP Cloud for Customer Integration with SAP ERP' having artifact 'Query Sales Order Pricing to SAP ERP'.
Since this is an outbound scenario from COD to ERP(request sales order pricing),
so the path should be '/cxf/COD/ERP/SALESORDERPRICING_REQUEST'.
Please let know further details on the error faced in both COD and HCI.
Regards,
Sangeeta
