DAX: Date Difference required with New Measure

Hi Anonymous

One more time, I need your help (Some change required in below DAX)

DDiff_RelDateCloDate = VAR Release = MAX ( 'Task'[ReleaseDate] ) VAR Closed = MAX ( 'Task'[ClosedDate] )
RETURN IF ( Closed > Release, DATEDIFF ( Release, Closed, DAY ), DATEDIFF ( Closed, Release, DAY ) )

Note: Sometimes [ReleaseDate] field is nodate : [ClosedDate] field is with date

                             [ReleaseDate] field is with date : [ClosedDate] field is no date

In that case DDiff_RelDateCloDate field need to be updated as "ReleaseDate is blank"  /  "ClosedDate is blank"

I can say thank you so much in advance!

Try this:

Daydiff =
VAR Release =
    MAX ( 'Task'[ReleaseDate] )
VAR Closed =
    MAX ( 'Task'[ClosedDate] )
VAR EarliestDate =
    MIN ( Release, Closed )
VAR LatestDate =
    MAX ( Release, Closed )
VAR NoOfDays =
    DATEDIFF ( EarliestDate, LatestDate, DAY )
RETURN
    SWITCH ( TRUE (),
        Release = BLANK (), "ReleaseDate is blank",
        Closed = BLANK (), "ClosedDate is blank",
        NoOfDays >= 21, "Met SLA",
        "NotMet SLA"
    )

A couple new variables.  EarliestDate is the smaller of the two variables Release and Closed.  LatestDate is the bigger of the two.

This lets you avoid the IF() statement by always putting the earlier date first in the DATEDIFF() function.

SWITCH( TRUE().... ) is a pretty well known pattern (you can find articles on it all over).  It basically is an easier to read nested If statement.

It says "if Release is blank then say 'ReleaseDate is blank'...else if Closed is blank then say 'CloseDate is blank'...else check if NoOfDays >=21., etc."

Hope this helps

Thanks for your time and support

Its not working correctly ! i enclosed some screen shots.

In Daydiff measure output : i need daysdiffarence, releasedate blank, closedate blank (only these 3 outputs required)

- I will make another measure for >= 21 SLA "Met SLA" "NotMet SLA"

Daydiff =
VAR Release =
    MAX ( 'Task'[ReleaseDate] )
VAR Closed =
    MAX ( 'Task'[ClosedDate] )
VAR EarliestDate =
    MIN ( Release, Closed )
VAR LatestDate =
    MAX ( Release, Closed )
VAR NoOfDays =
    DATEDIFF ( EarliestDate, LatestDate, DAY )
RETURN
    SWITCH ( TRUE (),
        Release = BLANK (), "ReleaseDate is blank",
        Closed = BLANK (), "ClosedDate is blank",
        NoOfDays
)

Not sure why "ReleaseDate is blank" is showing up in those rows.  Do you have any other filter context going on?

That updated measure will just output those 3 values.  You can display SLA elsewhere.

Anonymous Thanks

No filters applied

Might be some DAX error

If you get any accurate DAX please share with me

I posted this requirement on few days back no one replied

Please look into it if you have time

Day Diffarence excluding weekends

I created a Date table:

Dim Table=CALENDAR(DATE(2008,1,1),DATE(2018,12,31))

I created a new column with is working day or not

is work day = SWITCH(WEEKDAY([Date]),1,0,7,0,1)

Now I want to create "DateDifference" Column with Createddate & Closeddate (I want to know day diffarence b/w these two dates excluding weekends)

CreatedDate   ClosedDate  DateDiffarence

send me the link to that thread.  That way others can search for the thread and see the solution

Hi Anonymous Master,

Hope you are doing good.

The below provided Date Diffarence DAX is working fine.

DDiff_DueDateCloDate = VAR Due = MAX ( 'Task'[DueDate] ) VAR Clos = MAX ( 'Task'[ClosedDate] )
RETURN IF ( Clos > Due, DATEDIFF ( Due, Clos, DAY ), DATEDIFF ( Clos, Due, DAY ) )

I need some change from the Output

Example about DueDate & ClosedDate.

-- If ClosedDate is lessthan the DueDate output noofdays (+Positive number)

-- If ClosedDate is Greatherthan the DueDate output noofdays (-Negative number)

Please help me out this Master :)

Thank you so much Anonymous DAX Master :-)

Hi Anonymous,

One doubt from my end. Its a new one :-)

While applying below DAX i got one error.,

truecondiation = IF(ISM[OData_{CH} Recommend0]=BLANK(),ISM[OData_{RNSP} TSS_x00],ISM[OData_{CH} Recommend0])

Expressions that yield variant data-type cannot be used to define calculated columns.

Can you fix this for me.

Hi Anonymous

I have one doubt
