`PosReceivingLine`

One line of a receiving document, as stored. The POS buys by the case: quantities count CASES (purchase units of unitsPerCase sell units each) and costs are the cost of ONE CASE, exactly as the POS stores them. The API derives nothing: no unit cost, no extended total and no outstanding quantity is computed, no sign is changed and nothing is clamped. Divide a case cost by unitsPerCase yourself if you need a unit cost.

Type: object.

Name	Type	Description
`lineId` required	string	The POS line id.
`receivedQuantity` required	number	Quantity received, in CASES, signed as stored (a return to the vendor is negative; a stored null reads 0).
`amount`	number	The line amount as the POS stored it (the POS stores receivedQuantity x caseCost); never recomputed.
`caseCost`	number	Cost of ONE CASE after the document's discount, as stored. Not a unit cost.
`caseCostBeforeDiscount`	number	Cost of ONE CASE before the discount, as stored. Not a unit cost.
`costFlag`	string	The POS cost-flag letter of the line.
`description`	string	The item description on the line.
`discountAmount`	number	The line's discount amount, as stored.
`lineNumber`	string	The line's position on the document, as the POS shows it.
`modifiedAt`	string (date-time)	When the POS last modified the line (UTC).
`newProduct`	boolean	The line created the product in the POS.
`noDiscount`	boolean	The line is excluded from the document's discount.
`orderedQuantity`	number	The purchase-order line's quantity, in CASES, copied when the order was imported into this document: ordered next to received. On a line that did not come from a purchase order it is whatever the POS left there; the header's purchaseOrderId says whether the document had an order at all. The API never computes a difference.
`productCode`	string	The store product code.
`unitsPerCase`	number	Sell units in one case, as the POS copied it from the product when the line was written.
`vendorItemCode`	string	The vendor's own item code.
