Steps
Get the supplier's Purchase Order (PO) 1.0.0 WSDL — this is a distributor-to-supplier 'push' service, unlike the read-only services above
Build the PO payload using product/part identifiers and pricing sourced from the same supplier's Product Pricing & Configuration (PPC) service, since PO is designed to work in tandem with PPC
Submit the assembled purchase order XML along with the required ship-to/bill-to blocks to the supplier's PO endpoint
Capture the supplier's synchronous acknowledgment for the submission, then separately poll Order Status for downstream fulfillment updates
Known gotchas
Inbound PO submission is far less commonly supported than outbound Order Status/Inventory — verify the supplier actually accepts PromoStandards POs before integrating
PPC data must be fetched immediately before PO submission since pricing/configuration can change; stale PPC data causes PO rejections
A malformed or duplicate PO can create a real live order on the supplier's side — test only against a supplier-provided sandbox/test account during development
