4、 一個(gè)揀貨列表Picklist用于挑選倉(cāng)庫(kù)中的貨物，以便于打包運(yùn)輸。一個(gè)Picklist可以分配給 多個(gè)Bin（揀貨容器）。確定好的Bin也可能需要合并(merge)或者調(diào)整(transfer)。每個(gè)Bin的產(chǎn)品會(huì)分成多個(gè)不同的運(yùn)輸(Shipment)。一個(gè)PicklistBin包含多個(gè)PicklistItem。每 次揀貨的狀態(tài)變更都需要記錄在PicklistStatusHistory。 一個(gè)運(yùn)輸(Shipment)會(huì)有多個(gè)運(yùn)輸項(xiàng)(ShipmentItem)，每個(gè)ShipmentItem對(duì)應(yīng)運(yùn)輸?shù)奈?料(Product)，包括Product的數(shù)量。每次運(yùn)輸需要聯(lián)系人信息(ContactMesh

5、)。 每個(gè)運(yùn)輸項(xiàng)(ShipmentItem)有自己的多個(gè)賬目信息(ShipmentItemBilling)和多個(gè)發(fā)行信息(ItemIssuance)。運(yùn)輸項(xiàng)有自己的特性(ShipmentItemFeature)，并會(huì)生成運(yùn)輸項(xiàng)的文檔(ShipmentDocument)。業(yè)務(wù)規(guī)則 一個(gè)Shipment包含多個(gè)包裹ShipmentPackage，每個(gè)包裹的內(nèi)容ShipmentPackageContent對(duì)應(yīng)于運(yùn)輸項(xiàng)ShipmentItem。如果一個(gè)ShipmentPackage定義 了Receipt，說(shuō)明該包裹已運(yùn)輸，狀態(tài)從PURCH_SHIP_CREATED更新為PURCH_SHIP_SHIPP

6、ED。 一個(gè)ShipmentItem有多個(gè)Issuance，而每個(gè)ItemIssuance與OrderItem存在一對(duì)一關(guān)聯(lián)。 每個(gè)運(yùn)輸項(xiàng)(ShipmentItem)對(duì)應(yīng)一個(gè)ShipmentPackageContent。因此在獲得ShipmentPackageContent時(shí)，需要合計(jì)Issuance的值。 運(yùn)輸需要成本估算ShippingCostEstimate。估算的費(fèi)用取決于運(yùn)輸?shù)姆绞?、承運(yùn)商、運(yùn) 輸?shù)腝uantity Break，包括重量、數(shù)量、價(jià)格等。 一次運(yùn)輸需要規(guī)劃路線(Route)，每一個(gè)路線規(guī)劃都有一個(gè)運(yùn)輸方式。ShippmentShipmentItemProductShip
