Power Query max date from other table
Hi, I do exactly this in creating date tables in Power Query. Basically you create a reference to your original table, click on the Date column, then in the Transform tab, select the Date dropdown and select Earliest or Latest. It creates a scalar value.
You cannot use it as a parameter as a parameter dropdown, but if you create a filter, just tell the filter to day "date > Jan 1, 2020" then after the filter is created, change the #date(2020,1,1) to varStartdate (or whatever you called the value.
See my full article on the date table here, which has info on how to create these dynamic values to use in other places.
Thanks! this was very helpfull.

Great! Glad it helped.
edhans , thank you for such a great blog post (Create a dynamic date table in Power Bi). I have long wanted to tackle this inconvenient problem. Thank you very much.
edhans , just a question. In your post you mention:
Make sure automatic date logic is off in Power BI. Select File, Options and Settings, Options, Data Load. Uncheck “Auto Date/Time”. Leaving this checked will create all sorts of unnecessary hidden tables and columns. You’ve created a perfect Date table. Don’t let Power BI’s AI mess this up.
So can I safely assume if I have created a "perfect" Date table, which all my other tables who have dates are connected to in a relationship, then I can always switch this off?
