How to perform batch update operations on custom business object in s4hc from sap ui5

My requirement is, i want to perform multiple batch update operations on custom business object. while sending the request i'm getting the error like "Malformed URI", but while doing multiple batch create operations, it's executing well.

please help me how to do batch update operation?

Below is the code:

var oModel = this.getOwnerComponent().getModel("Parent_Data");

oModel.setUseBatch(true);

oModel.attachRequestSent(function () { sap.ui.core.BusyIndicator.show(); }); //hide busy oModel.attachRequestCompleted(function () { sap.ui.core.BusyIndicator.hide(); }); //hide busy if request is failed oModel.attachRequestFailed(function () { sap.ui.core.BusyIndicator.hide(); }); // oModel.setUseBatch(true);

for (var i = 0; i < oData.length; i++) {

var odataParent = oData[i]; // var payLoad = {}; // payLoad

.YProduct = oData[i].YProduct;

var sUpdatePath = "/YY1_PRODUCT_PARENTDATA(guid'" + odataParent.SAP_UUID + "')";

var sUpdatePath = "/YY1_PRODUCT_PARENTDATA(guid'" + odataParent.SAP_UUID + "')"; oModel.update(sUpdatePath, odataParent, {

method: "PUT",

success: function (oDataSuccess, oResponse) {

sap.m.MessageToast.show("Product Updated Successfully"); },

error: function (oResponse) {

} }); }

oModel.submitChanges();

i'm getting the below error:
