Hi, I was building a Budget Model with a customer of mine who already had a Forecasting model. A lot of Business Rules are different between Forecasting and Budgeting processes, but a lot of them are simlar. We are using copy and paste of formulas. We needed to switch between models, but that made us close all the active modules of the model we were leaving and reopening the relevant modules in the other modules. and again and again and again. It was a little boring process, opening closing, opening, closing, when I suddendly realized that we could re-open another Anaplan session in a second tab in the browser, The first Browser tab has the Budget Model open, and the second browser tab had the Forecasting model open, thus copy and paste between models and modules was much easier and faster. When we needed to create a specific view in a forecasting module to be used as a import source in the Budget module, it was also very quickly done. A little ashamed it took me one hour or so before I though to this very easy way to save time. KR Michel.
