I am working on one of the dashboard requirement for what if analysis. I have multiple columns, say Region, Country, State, City, numeric field1, 2, 3 and so on. Now, I need to have multiple combobox / filters based on first four columns and accordingly guage / any other component value should change as the user selects combo 1 or 2 or multiple combination. Also, the excel to be processed consists of row entries in millions to be very honest. This is POC, so there are no BEx queries / QAAWS / Live office as of now. How do I achieve multiple combo combination with large amount of data?
