Sample cXML Invoice Backed by Contract

Coupa allows to post non-PO backed invoices against contract via cXML.  The only difference in the spec from a PO backed invoice is that Document Reference payloadID in InvoiceDetailOrderInfo tag includes contract number instead of PO number under Master Agreement Reference.

<InvoiceDetailOrderInfo>
	 <MasterAgreementReference>
			<!-- payloadID is the Contract number -->
			<DocumentReference payloadID="2257" />
	 </MasterAgreementReference>
</InvoiceDetailOrderInfo>
