POST ASNs to /user/asn_headers using the supplier's Invoicing cXML credentials.

The following steps guide you through posting an ASN using cXML.

1. Decide on the supplier you want to test.
2. Log in to your Coupa instance and select the Invoicing tab.
3. Search for your supplier among the table results.
4. Verify the supplier's record. The suppliers credentials need to be populated since they're also used for cXML ASNs.
5. Create an order within Coupa for the supplier by submitting a requisition and approving it.
6. Modify the sample payload (shown in this same page below) so it's updated with the proper supplier credentials (from the supplier record, above) and order details (from the Orders tab).
7. Use your favorite REST API client to POST your modified payload the following URL: https://{customer_instance_name}/cxml/ship_notice_request.
8. Within Coupa, to go Setup > Spend History > ASNs at https://{customer_instance_name}/user/asn_headers The widow displays a table where each row is an ASN and columns provide information about each one.
9. Scroll to the right of the table results and verify that the <ShipmentIdentifier> from the payload is listed in the Tracking # column.
