if you're dealing with large datasets in tableau, try using calculated fields to create a
running total of sales over time instead of refreshing data extracts daily for each date range filter change ♂️. this reduces load times and keeps your dashboard snappy
// example calc field: running''total''sales = sum({ FIXED [date]: SUM() })by doing so, you can dynamically see trends without the performance hit of full data refreshes ⚡
