Purchase Order transmission using cXML

The following is a process workflow for purchase orders (POs) transmission using cXML. Note that the first 4 steps are generic and the same for all PO transmission channels (email, SAN, etc.)

  1. The user logs into Coupa.
  2. The user adds (punchout, catalog, or non-catalog) items to a requisition.
  3. The user submits the requisition for approval.
  4. Once the requisition is approved, Coupa generates a PO.
  5. Coupa sends the supplier the PO using OrderRequest cXML.
  6. The supplier receives the cXML and sends an OrderResponse cXML to Coupa.
  7. The supplier processes the order, delivers it to the user, and bills the user.

When a cXML PO fails to transmit to the supplier, the Coupa system immediately sends an email with details to the buyer admin. Read the rejection description from the supplier carefully.

In R19 Coupa added in-product cXML error monitoring. Here is a list of cXML PO transmission failures.

The most common errors are the following:
