DeletePurchaseOrderLineItemCommandRequestInput

Removes one position from an existing purchase order. A hard delete, not a flag. The order must be Open or Released, and the position must not have been delivered — the underlying procedure enforces neither, so both are guarded here. Deleting the last remaining position is rejected: an order without positions is not a valid document. Returns the full re-queried order, so the caller sees the recalculated result. - Request
