PurchaseOrderUpdateLineItem

One purchase order line that has a new expected date.

identifier
Type: string
required

How the supplier referred to the line. Matches the lineNumber you sent on the purchase order when Augment can resolve it; otherwise it is the identifier the supplier used, which is often a SKU and sometimes prose such as Line 2. Resolve it against your own lines before applying the dates, and route what you cannot match for review — this field is not a guaranteed reference to a line you sent.
expectedArrivalDate
Type: string | nullFormat: date

New expected arrival date for this line, as a UTC calendar day. Null when the supplier gave no new arrival date for the line.
expectedShipDate
Type: string | nullFormat: date

New expected ship date for this line, as a UTC calendar day. Null when the supplier gave no new ship date for the line.
note
Type: string | null

What the typed fields cannot carry — the supplier's account of why this line's dates moved.
