Help with 2018 and 2019 comparison (with different months)

[Rate]

Hello!!

I have a project that started on July 2018, with daily data for sales. We would want to include a comarison with the sales for 2018 (July to December 2018) against the sales form 2019 (January up to today).

For 2019 data I am using the Quick Measure for Total Year To Date and everyhing works great.

However, I am struggling enormously with the formula for the data for 2018. I have tried the following:

1. Of course, if I include a hard coded 2018 as a condition in the Calculate, the filters don't work.

2. I have tried with SAMEPERIODLASTYEAR, as everyone recommends, but in my case, as I don't have data for a full year, is not viable.

3. I tried DATEADD from my Dates table, but I only get blanks.

    DATEADD(
        Date.[Date], -1, YEAR))

Do you have any suggestions on another method that I could use?

Thanks a lot and kid regards!!

Hi @Rate ,

As suggested, you could create a calendar table with CALENDARAUTO() and then you could create the measure like below.

2019 = TOTALYTD(SUM('Data'[Sales]),'Table'[Date])
2018 = var a =DATEADD('Table'[Date],-1,YEAR) return TOTALYTD(SUM('Data'[Sales]),a)

Here is the output.

You also could refer to my attachement.

Can you try this 

Measure=calculate( sum(sales),parellelperiod(Dimdate(date),-1,year))

@Rate do you have date dimension in your model? if no you need to add one and  there are may posts on how to add one. Also make sure date dimension table is marked as date table .
