Hi Virinchy, very thanks for quick respond. I know it can be replaced with any other model but may i know where can i find and fill it if i created with mock data? Is it i need to write myself or there is a file contain it that can let me copy and paste and replace the highlighted line? If yes, mind you suggest me where it is?
Second question is if i create the apps by connecting Gateway in order to expose the data in the front end, is it i need to change the highlighted row (var oModel = new sap.ui.model.json.JSONModel("test-resources/sap/viz/demokit/dataset/bookstore_fiori/ByItemCity_sum.json");)instead of using JSON model? if yes, i am not sure whether i should change in this way (var oModel = new sap.ui.model (" ???"); )? And what parameter should i replaced with the question marks which i bold it? And where can i find it? Is it can find it in the metadata.xml which the 2 links that i highlighted?
Regards,
Loh.
