例として、1回の呼び出しで100個の新しい商品を作成したい場合、最も簡単な方法は、$ batch要求を使用して100個のPOST呼び出しすべてを単一のサービス呼び出しにまとめることです。

メソッドCHANGESET_BEGINを使用すると、新しい変更パラメータCV_DEFER_MODEが一度に処理できるゲートウェイフレームワークになります(遅延処理)。 この方法を実行するときの簡単な例を見てみましょう。
- Transaction /nsegw
- ランタイム成果物を展開します。
- dpc_extクラスをダブルクリックして
- / IWBEP / IF_MGW_APPL_SRV_RUNTIME〜CHANGESET_BEGINメソッドを見つけて、再定義してください。
その後、これを行うと、CHANGESET_BEGINメソッドは/ IWBEP / IF_MGW_APPL_SRV_RUNTIMEインターフェースから継承されます。

最初に、以下のようにoDataModelを設定する必要があります。
var oConfig = {metadataUrlParams: {},json: true,// loadMetadataAsync : true,defaultBindingMode: "OneWay",defaultCountMode: "None",useBatch: true};// Create and set domain model to the componentvar oModel = new sap.ui.model.odata.v2.ODataModel(sServiceUrl, oConfig);this.setModel(oModel);
その後、必要に応じて$ batch処理を実装できます。 私はそれのすべてをsap.m.tableを書かなかった、あなたはこのリンクでそれをチェックすることができる。

In your view , you need to bind oViewModel that is a json Model like this.<Table id="yourTableId" items="{ path: 'oViewModel>/yourArray' }" class="sapUiSizeCompact">
コントローラで、onInit関数でoViewModelをインスタンス化します。
this_oView = this.getView();var oViewModel = new sap.ui.model.json.JSONModel({yourArray: [{ "field1" : "data11","field2" : "data12","field3" : "data13"},{ "field1" : "data21","field2" : "data22","field3" : "data23"}]});this._oView.setModel(oViewModel, "oViewModel");
_getViewModel: function() {var oViewModel = this._oView.getModel("oViewModel");return oViewModel;},yourFunction: function() {debugger;var oModel = this.getView().getModel(),oTable = this._oTable, // Your Table that you will get item's data.iLength = oTable.getItems("items").length,oItem,sPath,bError = false;// Distinguish your request from other batch requests like below.oModel.setDeferredBatchGroups(["myId"]);for (var i = 0; i < iLength; i++) {var oEntry = {},oParams = {};// You need to show your message that returns from backend the latest.if (i === (iLength - 1)) {oParams.success = function(oData, oResponse) {sap.ui.core.BusyIndicator.hide();MessageToast.show(this._oResourceBundle.getText("PROCESS_SUCCESS"));// debugger;}.bind(this);oParams.error = function(oError) {// debugger;sap.ui.core.BusyIndicator.hide();var oJson = JSON.parse(oError.responseText);this._bIsError = true;var oJson = JSON.parse(oError.responseText);var oMsgBox = sap.ca.ui.message.showMessageBox({type: sap.ca.ui.message.Type.ERROR,message: oJson.error.message.value});if (!sap.ui.Device.support.touch) {oMsgBox.addStyleClass("sapUiSizeCompact");}oModel.refresh();}.bind(this);}oParams.async = false;oParams.batchGroupId = "myId";oItem = oTable.getItems("items")[i];sPath = oItem.getBindingContextPath();// needing to bind yourSpecific Json Model to Table's item aggregation.
// in this scenario, oEntry = this._getViewModel().getProperty(oItem.getBindingContextPath());sap.ui.core.BusyIndicator.show(0);oModel.create("/YourEntitySet", oEntry, oParams);}if (bError === true) {return;}oModel.submitChanges({groupId: "myId"});
