Sales Budget
See KB2221810 for uploading XLSX file as data source for the model. Only those with Birst Enterprise License can perform this operation.
See KB2307104 for using data lake as data source for the model, which is populated by M3 Demand Planner. It is also used for direct import of budget data coming from any other source, similar to uploading XLS directly to Birst. For this approach, Birst Enterprise License is not a prerequisite.
