With a previous version of Power BI, I have created this basic calculated column
MaxDate = If(ColDate = Max(Coldate), 1, 0)
Now, with the version of June 2019, NewColumn = Max(ColDate) occurs an unexpected errors.
And yes, the format of my column is Date (not text)
That is really strange
I can't reproduce the issue in Power BI desktop version 2.70.5494.661 64-bit (June 2019) which is released on 6/12/2019. Please update the Power BI desktop to this new version then test again.
