Introduction to CBI schema differences compared to ISO20022

CBI schemas use ISO20022 schemas as base, but with minor modifications making it a subset of ISO20022. In addition, the root tags are vastly different. In ISO20022 a <Document> is defined as root:

 

CBI, however, offers two different roots:

• <CBISDDReqLogMsg>
• <CBIBdySDDReq>

 

 

 

So when a valid ISO20022 payment file would start as

<?xml version="1.0" encoding="UTF-8"?>
<Document xmlns="urn:iso:std:iso:20022:tech:xsd:pain.008.001.02">
    <CstmrDrctDbtInitn>
        <GrpHdr>

Valid CBI file stars as:

<?xml version="1.0" encoding="UTF-8"?>
<CBISDDReqLogMsg xmlns="urn:CBI:xsd:CBISDDReqLogMsg.00.00.06">
    <GrpHdr>
        <MsgId>a</MsgId>

or alrernately:

<?xml version="1.0" encoding="UTF-8"?>
<CBIBdySDDReq xmlns="urn:CBI:xsd:CBIBdySDDReq.00.00.06" xmlns:LMSG="urn:CBI:xsd:CBISDDReqLogMsg.00.00.06">
    <PhyMsgInf>
        <PhyMsgTpCd>INC-SDDB-01</PhyMsgTpCd>
        <NumLogMsg>2</NumLogMsg>
    </PhyMsgInf>
    <CBIEnvelSDDReqLogMsg>
        <CBISDDReqLogMsg>
            <LMSG:GrpHdr>

 

if <PhyMsgInf> is desired to be present in the file.

 

 

These examples use pipe

• CBI Direct Debit v.00.00.06

as reference. Two structurally valid example files for this pipe is provided in the attachments.
