Create drop-ship purchase orders from sales-order lines
Creates one draft drop-ship purchase order per vendor for the supplied sales-order
lines. This is the API surface of the SO-side drop-ship creation wizard: it flips the
chosen lines to drop-ship, releases any confirm-time inventory reservation / backorder
for the drop-shipped quantity (so the units are not double-committed), splits a line
when only part of its quantity is drop-shipped, resolves a non-null purchase cost per
line (vendor purchase policy, then catalog cost, then the caller-supplied unit_cost),
and creates the draft POs through the same canonical handler the automatic
confirm-time cascade uses. Each created PO carries source_order_id back to this order
and is left in DRAFT / unsent state so it can be reviewed and sent (or cancelled) before
the vendor sees it. Kit-component, service, box, and already-linked lines are rejected
with a specific code. Requires purchasing:write scope. Idempotent via
Idempotency-Key header.
