create destination and add neo-app.json add something similar
{
"path": "/sap/opu/odata",
"target": {
"type": "destination",
"name": "NAME_OF_DESTINATION",
"entryPath": "/sap/opu/odata"
},
"description": "Target OData system"
},
so you have to use yout model as
var sServiceUrl = "/sap/opu/odata/sap/Z_RFC_BOR_SALES_SRV/";
var oModel = new sap.ui.model.odata.ODataModel(sServiceUrl,false);
without specifying server name and port
