Post PatronDifference between two columns and finding the Average it
Dear All,
Please help me to write the formula to find the difference between two date columns and then take the average of that.
Below is the sample
| LAST_UPDATED_DATE | CREATION_DATE | DAY DIFF | |
| 10/4/2018 0:00 | 9/30/2018 0:00 | 4 | Average =1.428571429 |
| 10/1/2018 0:00 | 9/30/2018 0:00 | 1 | |
| 10/1/2018 0:00 | 9/30/2018 0:00 | 1 | |
| 10/1/2018 0:00 | 9/30/2018 0:00 | 1 | |
| 10/1/2018 0:00 | 9/30/2018 0:00 | 1 | |
| 10/1/2018 0:00 | 9/30/2018 0:00 | 1 | |
| 10/1/2018 0:00 | 9/30/2018 0:00 | 1 |
Average to be shown in the CARD visual.
Thanks in advance
Hi Greg_Deckler
Calculated Column for DATEDIFF is throwing an error saying "Function DATEDIFF is not allowed as part of calculated Column DAX expressions on DirectQuery models.
So I tried the DATEDIFF with Measure and it's accepting only with aggregate function like MIN,MAX etc,like below
1.DAY DIFF = DATEDIFF(MIN('Table1'[LAST_UPDATED_DATE]),MIN('Table1'[CREATION_DATE]),DAY)2.AVG OF DAY = AVERAGEX('Table1','Table1'[DAY DIFF])It's working fine.Thank you so much for your timely support.

Well, you should be able to create a column:
DAY DIFF = DATEDIFF([LAST_UPDATED_DATE],[CREATION_DATE],DAY)
And then a measure:
Average of DAY DIFF = AVERAGEX('Table',[DAY DIFF])

Glad you got it sorted out. Yeah, DirectQuery causes some issues with certain DAX functions.
