Assigns a supplier to a proposal item and pulls that supplier’s cost onto it. The supplier must be one returned by list item suppliers for this item; anything else returns 404.

The change always covers every item in the proposal that comes from the same source item and shares its item type. It cannot be narrowed to the item named in the path.

Each item that moves to the new supplier takes that supplier’s catalog cost, replacing any cost entered on it, and ends up with no cost at all where the supplier has none for that item. Items already using this supplier are left alone — they keep the cost they carry, hand-entered or not, and are still listed in the response. If the company is not yet linked to the supplier, the call links it. The response lists every matched item, including ones already using this supplier, and carries the supplier as a display name only. To confirm which supplier id is now in use, re-read list item suppliers and look for isDefault: true. SetDefault also makes this the company’s default supplier for the catalog item, and updates the company’s draft proposals and draft orders that carry the item without a cost of their own.
