Need help to measure days between to dates in a column, with a twist

[niklasgrundel]

Hi, 

I need help to calculate days between column A and column B, the result should be presented in column C. I´ve managed to calculate days between A and B if they both contain dates. The twist is that I wan´t to use present day and calculate with order day if delivery date is missing. So column C should always present data.

I´m not really sure if this can be accomplished using Dax...

I´ve tried this code in a Power Query but it won´t work:

if ['Delivery date']=""

then (DateTime.Date-['Order date'])

else

(['Delivery Date']-[#"Order date"])

Thanks in advance!

Hi @niklasgrundel 

In Power query you can create a custom column

= if [Delivery Date]="" or [Delivery Date]=null 
then Date.From(DateTime.LocalNow())-[Order date]
else [Delivery Date]-[Order date]

In DaX you can create a calculated column:

Column = 
IF(ISBLANK([Delivery Date]), DATEDIFF([Order Date], TODAY(), DAY), DATEDIFF([Order Date], [Delivery Date], DAY) )

Thanks @az38 for quick reply!

I manged to get you DaX-code to work as you can see below, the Power query won´t show and present days where the delivery date column is missing data, can it be a problem with Date.From(DateTime.LocalNow())?

Hi @niklasgrundel 

try null without quotas in Power query, just = null

- To quote or note to quote, that´s the question!? 😉

When I removed the quotation of null your Power Query script worked aswell.

Thanks for your patience and help!

There is no question, if I see null 🙂

Good luck!
