Quote to Order Reference in punchout

Question

I am trying to figure out how to maintain the quote to order reference when a buyer retrieves a quote/order from my punchout catalog.

What I mean by this is, when the supplier catalog sends back the products to the buyer's requisition system in a "PunchoutOrderMessage" There is no place for the supplier to enter a quote id. I have looked through the cxml spec but I am not seeing anything. Am I missing something?

I have included a sample "punchoutordermessage". Can anyone help me figure out how to send a quote ID back to the buyer?

Answer 1

We are going to use the extrinsic elements.

    <ItemIn quantity="1"> 
         <ItemDetail> 
           <UnitPrice> 
               <Money currency="USD">1.23</Money> 
          </UnitPrice> 
          <Description xml:lang="en-US">product 123</Description> 
          <UnitOfMeasure>FT</UnitOfMeasure> 
          <Classification domain="UNSPSC">31151601</Classification> 
          <ManufacturerPartID>1234</ManufacturerPartID> 
          <ManufacturerName>Test Company</ManufacturerName> 
          <Extrinsic name="QuoteId">12345</Extrinsic>
          <Extrinsic name="QuoteLine">1</Extrinsic>
         </ItemDetail> 
   </ItemIn>
