Date Difference with blank values

  Hi,   I'm trying to calculate the number of days between two dates and for one of these columns, there may be blanks which I want to ignore (rather than give a large -ve value).   What DAX do ...

    Hi ManNVSM,

     

    Thanks for your help. You gave me the idea of using dummy data so I did this and came up with this formula:

     

    Days to close = if('Breach Register'[Breach closed date]=BLANK(),'Breach Register'[Breach closed date],1.0*'Breach Register'[Breach closed date]-'Breach Register'[Date that breach discovered])

     

    This seems to work ok.

     

    Thanks for your help again.

Dear Bimster,

 

You need to combine your DateDiff DAX with IF.

Ex:    New Day to close =   CALCULATE( IF ( CLoseDate <> blank(),   [your DateDif Formular] , ""))

 

Regards,

ManNVSM.

    Hi ManNVSM,

     

    I just tried this and am getting the above error:. Any idea on how to resolve this. The underlying data is being pulled through from a SharePoint list.

      Dear Bimster

       

      Try this again with ALLEXCEPT.

      Ex: New day to close = CALCULATE(IF('Breach Register'[Breach closed date] <> BLANK(),DATEDIFF('Breach Register'[Date that breach discovered],   'Breach Register'[Breach closed date], day)  
      , ALLEXCEPT ('Breach Register'[Title]))

       

      Regards,

      ManNVSM.

        Thanks for the help. I've tried this with the allexcept addition and the same error message is appearing.

         

        It seems to be very complicated to do a date difference whilst ignoring blanks.
