We are implementing BCM. Our payment file formats like US ACH and Wires are based on SEPA_CT which generates the XML file formats. (pain.001.001.03). Our SAP PI(XI) system has the Swift integration package for SAP (SIPS) installed. As far as I know from the documentation available SIPS package converts the MT101 kind of formats to XML version and sends them to SwiftNet and then to bank. Since in our case we are already generating the XML files as per ISO20022 standards we are unable to understand the purpose of SIPS package in PI. It would be very helpful if someone who has gone through this kind of implementation can answer this for us.
