Need Help calculating hour difference with datediff function

[Anonymous]

Hi everyone,

I am using a calculated Column "Hours" to calculate the hour differences between created and resource confirmed. The formula I am using is: 

Hours to Assign = DATEDIFF((CRQ_TASKS[Received]), (CRQ_Tasks[ResourceConfirmed]), HOUR)

However the results aren't all accurate especially for higher values. See Task 3 for example, it shows 105 hours but if you look at the date created and date confirmed it shows that its on the same day. The hours should be negative, if anything, since date created is later than date confirmed (entry error by user). When I switch the formula to MINUTE, the same thing happens. Task 11 shows 2 hours but it is still a wrong calculation.

The hours variable shows the same values regardless of "dont summarize" or "average". 

Any ideas on how to calculate hours in terms of 0.## or in hours and minutes accurately? Also why is this error occurring?

Thanks!

The sample data is as follows:

Hi @Anonymous ,

In fact, datediff function works on my side. Can you please provide a sample pbix for test?

Hello,

I tried your formula with the sample data you provided and can't reproduce the same result. For hours i get 0 for Task3 and for minutes i get -3. 

Maybe you can give more details or share your pbix (hide sensitive data if it is the case) to test.
