如何通过ui5中的odataModel.create为2个或多个实体集创建条目

我有一个OData服务,有4种实体类型——地址、抄送、标题、项目、评论。 在用户按下“订单”按钮后,我想使用此服务在后端创建一个条目。有一个标题和相关项需要传递。

后端的OData服务:

{
  "d" : {
    "__metadata" : {
      "id" : "http://.../sap/opu/odata/sap/ZOrders/HeaderSet('3898')",
      "uri" : "http://.../sap/opu/odata/sap/ZOrders/HeaderSet('3898')",
      "type" : "ZOrder.Header"
    },
    "CompanyID" : "W",
    "StockRoomID" : "A",
    "SalesDocument" : "3898",  


"ItemSet" : [
        {
          "__metadata" : {
            "id" : "http://.../sap/opu/odata/sap/ZOrders/ItemSet(SalesDocument='3898',SalesDocumentItem='000010')",
            "uri" : "http://.../sap/opu/odata/sap/ZOrders/ItemSet(SalesDocument='3898',SalesDocumentItem='000010')",
            "type" : "ZOrders.Item"
          },
          "SalesDocument" : "3898",
          "SalesDocumentItem" : "000010",  //Line item number
          "StockRoomID" : "A",
          }
      ]
   }
}

控制器JS

 buttonClick: function(event) {
    var sServiceURl = this.getOwnerComponent().getMetadata().getManifestEntry("sap.app").dataSources["ZOrders"].uri;
   this.OdataModel = new sap.ui.model.odata.v2.ODataModel(sServiceURl);
   var model = vc.getView().getModel();

   var oEntry = {};
   oEntry.CompanyID = model.getProperty("/CompanyID");
   oEntry.StockRoomID = model.getProperty("/StockRoomID");
   oEntry.SalesDocument = model.getProperty("/SalesDocument");



    //Now want to pass items data to service so 
    //Creating an empty ItemSet array, pulling data from model.

    //But my logic is wrong here for sure. 
            var itemData = [];

            var itemsArray = v.getProperty("/ItemSet");

            for (var i = 0; i < itemsArray.results.length; i++) {
            itemData.push({
                    SalesDocument: itemsArray.results[i].SalesDocument,
                    SalesDocumentItem: itemsArray.results[i].SalesDocumentItem,
                    StockRoomID: itemsArray.results[i].StockRoomID,

                });

            }
            oEntry.ItemSet = itemData;

     this.OdataModel.create("/HeaderSet", oEntry, this._submitOrderSuccess.bind(this), this._submitOrderError.bind(this));

**调试器-头负载**

{  
   "CompanyID":"RSW0",
   "StockRoomID":"A200",
   "SalesDocument":"4053",
   "Return":"X",
   "Reason":"101",
   "ItemSet":[  
      {  
         "SalesDocument":"4053",
         "SalesDocumentItem":"000010",
         "StockRoomID":"A200",
         "ReturnItemFlag":"X",
         "QtyToReturn":"1.000"
      },
      {  
         "SalesDocument":"4053",
         "SalesDocumentItem":"000020",
         "StockRoomID":"A200",
         "ReturnItemFlag":"X",
         "QtyToReturn":"1.000"
      },
      {  
         "SalesDocument":"4053",
         "SalesDocumentItem":"000030",
         "StockRoomID":"A200",
         "ReturnItemFlag":"X",
         "QtyToReturn":"1.000"
      }
   ]
}
