cannot check if [date-time column] is null in dataflow. same logic worked before and still works in power bi desktop.
I used M syntax: if [date-time column] = null then else.
However, the check null logic stopped working since early this week. BUG?
Hi @Anonymous ,
Based on my test, I cannot reproduce your issue here. Could you please share your code to me or you can just press the code manually to have a try.
Table.AddColumn(#"Changed Type", "New column", each if [Date] = null then "2" else [Date])
please see the following example.
the 1st row in the [Forecast] column shouldn't be null
