Where have I gone wrong with datediff measure?

[richrich123]

Morning,

Just looking to apply conditional formatting to cases that are overdue updates. In this example, the last update is far greater than 2 days but is still showing 0. Have I got something wrong in the measure or is if for some reason not recognising the date?

@Idrissshatila , hi and thanks for the suggestion. I have tried swapping today() to before my selected date but it then is only offering me to compare to measures in the case data and not my selected date? All those in the drop down are measures only and don't contain any fields e.g my lastupdated filed.

Hello,

can you paste the first measure here

[richrich123]

@Idrissshatila 

Older than 2 days = IF( DATEDIFF(SELECTEDVALUE('Case'[lastcustomerupdate].[Date]),TODAY(), DAY) > 2,1,0)

[Idrissshatila]

Try it like this

Older than 2 days = IF( DATEDIFF(TODAY(), SELECTEDVALUE('Case'[lastcustomerupdate].[Date]),DAY) > 2,1,0)

[richrich123]

Thanks, it accepted that measure but its still returning 0 for every item including those over 2 days?

[Idrissshatila]

try it now :

Older than 2 days = IF( DATEDIFF(SELECTEDVALUE('Case'[lastcustomerupdate].[Date]),TODAY(), DAY) < -2,1,0)

[richrich123]

@Idrissshatila , frustratingly still returning a 0 for the example that is weeks old 

[Idrissshatila]

Weird, you're sure its the right date field that's referenced in the dax measure?

[richrich123]

@Idrissshatila Have double checked and also removed and re-added fields. You can see the date field and the dax measure both tie up and are the same measure and date field in the measure as is applied to the table fields? Have double checked and all looks spot on 

Checked it is 100% formatted as a date field as well and all fine

[Idrissshatila]

Try this:

Older than 2 days = IF( DATEDIFF('Case'[lastcustomerupdate],TODAY(), DAY) >2,1,0)

[richrich123]

[Idrissshatila]

then lets try it like this

Older than 2 days = IF( DATEDIFF(SELECTEDVALUE('Case'[lastcustomerupdate].[Date]),TODAY(), DAY) >2,1,0)

[richrich123]

The measure works but again, output for a date far greater than 2 days old is still zero.

Hi @richrich123 ,

According to your description, here are my steps you can follow as a solution.

(1) This is my test data.  

(2) We can create a measure.

Older than 2 days = 
IF(DATEDIFF(SELECTEDVALUE('Case'[lastcustomerupdate]),TODAY(),DAY)>2,1,0)

(3) Then the result is as follows.
