DATEADD Function
Hi All. Got a curly one here. I am working with a table which has placements. The data is from 2015, In order to calculate the conversion rate, I need to select records from 2015 uptto 60 days prior from today (which is going to rolling on daily basis) .
I have been using a calculate formula for conversion rate (which is simply placements / Claims) with dateadd function (date, -2, months). The formula works fine when I view this on a card visual but when I pull it on a table against state, site or any other field from the same table, it throws an error "DATEADD expects a contigous selection when date column is not unique, has gaps or it contains time portion".
Hi Anonymous ,
You may create measure like DAX below.
Measure= CALCULATE(<claim ID / Placements measure or coulmn>,FILTER(ALLSELECTED(Sales),Sales[Date]<=DATE(YEAR(TODAY()), MONTH(TODAY())-2, DAY(TODAY()))))Best Regards,

Hi, are you using a date or calendar table for your dates (i.e a single table with continuous dates)? If not then you will need to remodel. here is an example of a date table created using DAX; https://www.sqlbi.com/tools/dax-date-template/
here is a more basic version : https://www.sqlbi.com/articles/creating-a-simple-date-table-in-dax/
Alberto and Marco have lots of good tutorials on this.
Dateadd needs continuous dates. That is why we recommend having a date table. There is an alternate
New date=date(year([Date])-1,month([Date])-1,day([Date])-1)
This mean new date is one year, one month and one day behind
New date=date(year([Date])-1,month([Date]),day([Date]))
One year behind
To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :

Tried this formula and came up with the following error:
"An argument of function 'DATE' has the wrong data type or the result is too large or too small."
Basically what I am trying to achieve is for my conversion rate, select everything from 2015 up until 2 months from today.
So current month being April, select all records from 2015 - February 2020.
My formula would be something like:
Conversion Rate = CALCULATE (claim ID / Placements) where placement date is up until latest_placement_date - 2 months.
