SAPUI5 - batch operations - how to do it right?
I got several EntititySets that I want to update in my SAP backend, so I fetch my data (payload) as JSON and put it in the request (its successful in node "data"):
code:
var oTreeJSON = oTreeTable.getModel().getProperty("/root");
var oModel = sap.ui.getCore().getModel();
var batchChanges = [];
for (var i = 0; i < oTreeAll.length; i++) {
batchChanges.push(oModel.createBatchOperation("/sap/opu/odata/sap/MY_SERVICE/?$batch", "POST", oTreeAll[i]));
}
oModel.submitBatch();
My request looks like this:
Where should it arrive at SAP (which method)? What am I doing wrong, there is no error anywhere, but no call came through in my backend ... Glad about every hint! Thank.
Working example with reduced complexity:
var oEntry = {};
oEntry.MyId = "00000001";
oEntry.Value = "300";
batchChanges.push(oModel.createBatchOperation("MyEntitySet", "POST", oEntry, null));
oModel.addBatchChangeOperations(batchChanges);
oModel.setUseBatch(true);
oModel.submitBatch();
For the record, method calls:
- 1) / IWBEP / IF_MGW_CORE_SRV_RUNTIME ~ CHANGESET_BEGIN: SAP EXIT clause.
- 2) / iwbep / if_mgw_appl_srv_runtime ~ create_entity. (n-times) // make your stuff with entity
- 3) / iwbep / if_mgw_core_srv_runtime ~ changeset_end: SAP clause COMMIT RUN.

Submit my POST code for sap.ui.model.odata.v2.ODataModel
"models": {
"": {
"dataSource": "mainService",
"preload": true,
"settings" : {
"useBatch" : true,
"defaultBindingMode": "TwoWay",
"defaultCountMode" : "None",
//default is sap.ui.model.odata.UpdateMethod.Merge
"defaultUpdateMethod" : "Put"
}
}
}
var sPath = oView.getBindingContext().getPath();
oModel.setDeferredGroups(["editGroup"]);
oModel.update(sPath, oData, {groupId: "editGroup"});
oModel.update(sPath, oData2, {groupId: "editGroup"});
oModel.submitChanges({
groupId: "editGroup",
success: this.successCallback,
error: this.errorCallback
});
Actually v2.ODataModel will use Batch by default, use update()
/ create()
/ delete()
without setDeferredGroups()
and submitChanges()
ok. But in this case I get a callback for every request I use submitChanges
to combine the responses into one.
