Review Times

[Anonymous]

Hello, 

I need to calculate the difference between 2 date columns to determine how long a review took for each project. I need to do this for each row in the table not the columns as a whole. Does anyone know if and/or how this can be done?

@Anonymous , please check the pbix. There are a few ways date diff has been taken within the table across tables.

Hey @Anonymous 

Assuming you just need days and not time this is possible, thought depending on what your data looks like it can get complicated.

First suggestion is to see if you can use DATEIFF like in this thread: https://community.powerbi.com/t5/Desktop/Calculate-difference-between-two-date-time-values/td-p/71841

If that does not work then you can try adding an Age column in the query like in this thread: https://community.powerbi.com/t5/Desktop/Difference-between-two-dates-DAX/td-p/157320

The simplest solution that often doesn't work is to subtract the two and multiple by 1. to give you a numerical value for the date as in this thread: https://community.powerbi.com/t5/Desktop/calculate-number-of-days-between-2-dates/td-p/51213

Let me know if none of these work for you.

If this helps please kudo.

My formula is this-

Day= DATEDIFF('Dates'[Complete Final App Received] , 'Dates'[Final App Approved], Day)

I keep get this error-

"A single value for column 'Complete Final App Received' in table 'Dates' cannot be determined. This can happen when a measure formula refers to a comlun that contains many values without specifying an aggregation such as min, max, count or sum to get a single result."

I just need to know how many days passed between the dates in each of these columns in my table.

Hi @Anonymous 

If you select "create measure", then use the formula below:

Day= DATEDIFF(MAX('Dates'[Complete Final App Received]) , MAX('Dates'[Final App Approved]), Day)

If you select "create calculated column", use the formula you provided.
