Hi im trying the most simple query. Any help? if ([Actual End Date] < [Target End Date]) then 1 else 0 If date1 is less then date2 then put 1 in the column otherwise put 0.Error: Expression.Error: We cannot convert the value null to type Logical.Support?

if ([Actual End Date] ?? #date(1,1,1)) < ([Target End Date] ?? #date(1,1,1)) then 1 else 0

Create a new column on if statement(Very basic support needed)

  Hi thanks for answering. I need to do the same thing but replace [Actual End Date] with Today() or something which works simular:
  if (DateTime.Now() < ([Target End Date] ?? #date(1,1,1)) then 1 else 0
  Something simular to above should work. Any support?

I have tried on this dummy data and it is working as per your requirement.
I added one custom column with the formula mentioned below:
Try this and if my solution solves your doubt then please consider it as a solution.

You have a null in one of your date fields, so null > date isn't valid. Try each if is null [Actual End Date] or [Actual End Date] < [Target End Date] then 1 else 0
