The DAX function documentation in MSDN can be found on separate pages, organized by function categories and then details for every function. This is useful but you can’t view all of the functions in one searchable page. If you don’t know exactly what you’re looking for, it can be a bit of a hunting expedition. I find that sometimes it is convenient to have all of the documentation in one list, making it easier to find the function I’m looking for.
I’ve organized the complete set of 2016 DAX functions for SSAS Tabular, Power Pivot and Power BI in two different views; grouped by function category and in one single list. Using Excel Online, the lists can be sorted, searched and filtered. I hope this is useful.
