Date issue

Hi,
 
Here is my issue:
I am trying to get the difference between two dates (I am using a direct query view), but on PBI desktop, I don’t see my fields as date format:

If anyone has any idea on why I cannot use the dateDiff or why I cannot see the date format for my two fields I will be more than happy.

 

thanks,

Naïma

    Kasiop - What happens if you do this:

     

    Measure = (MAX([Closure Date]) - MAX([Creation Date])) * 1.

     

    ?

      Thanks, it returns -40 does it mean I use this formula?

        Hi,

        after applying the formul, i am not sure the outcome is right... if you have another idea... that will be great.

        Thanks

    Hi Kasiop ,

     

    You may select on the column [Closure Date], go to Column tools->Data type, change the data type to Date, do the same with column [Creation Date]. Then you may create measure instead of calculated column like DAX below.

     

    Measure= DATEDIFF(MAX(Table1[Creation Date]),MAX(Table1[Closure Date]),DAY)

     

    Best Regards,

      Thanks Amy, but it is "kind of" a format date already but I still cannot use the Dax measure:

        Hi Kasiop ,

         

        Based on my test which connect to SQL Server database using DirectQuery Mode in the latest version of Power BI Desktop, the DATEDIFF function works well.

         

         

        DateDiff = DATEDIFF(MAX(Sales[CreationDate]),MAX(Sales[ClosureDate]),DAY)

         

         

         

        >>Thanks Amy, but it is "kind of" a format date already but I still cannot use the Dax measure: 

         

        Is there any error message to appear when you create this measure?

         

        Best Regards,
