Is it Possible to do Dax Calculations when we use Direct Query ?

Hi harshaSampath81,

You can write some DAX functions even in Direct Query mode. You need to select File > Options and then Settings > Options and settings > DirectQuery, then selecting the option *Allow unrestricted measures in DirectQuery mode**. When that option is selected, any DAX expression that is valid for a measure can be used. The functions that are supported vary by data source, but Intellisense will prompt you with only the valid options are you enter your formulas.
