Comparing two dates when one field is text and the other a date

Hello

 

I'm hoping someone can help. In my data I've got two different fields. An opened date and a closed date. My opened date always contains an date so the format is date. The closed date doesn't always contain a closed date so may sometimes contain "NULL".

 

This field is then formatted as text and when I try to work out the difference between the 2 dates I get an error.

 

As this is the way the dat pulls through from the source data I'd ideally not like to have to replace blanks etc.. within PowerBI but put it in the formula.

 

I want to write =IF(opened_date)=(closed_date),1,0)

 

Please help

 

Thanks

    For the NUll, we have a function IsBlank() could be used.

    You could first check if the closed date is blank first.

    The formula should be changed as below:

    IF(Or(!(opened_date)=(closed_date), IsBlank(closed_date)),0,1)

      Thanks Michael, however when I try this I still get the error below

       

      The syntax for '!' is incorrect. (DAX(IF(Or(!(opened_date)=(closed_date), IsBlank(closed_date)),0,1))).

        My bad.

         

        Try the following:

        IF(Or(not((opened_date)=(closed_date)), IsBlank(closed_date)),0,1)
