DATEADD With Inconsistent Date Range

Hi All-

 

I have searched for days on YouTube and the web trying to find solve for the folllowing issue, and hope someone here can help.  I have the following dataset that includes sales by store for the last 3 years.  When I try to calcuate prior year sales using the DATEADD function, I receive the following error.  I believe it is due to the fact that the dataset includes new stores that do not have a prior year to reference.  Has anyone found a solution for how to get the DATEADD function to work in this case?  I have found a workaround by using the PARALLELPERIOD function when calcualting MTD, QTD, and YTD, however I want to include a custom date filter in my slicer, and need to utilize DATEADD so that it will calculate exactly 365 back from the specified date range.

 

My fact table: tbl_ReportData

My date table: tbl_Date

 

I created separate a custom sales measure (in addition to MTD, QTD, and YTD measures I have also created.  I have a disconnected table that I am using with the slicer):

Custom Sales =
CALCULATE(
    [Total Sales],
    FILTER(
        tbl_Date,
        tbl_Date[Date] >= MIN(tbl_ReportData[Date]) &&
        tbl_Date[Date] <= MAX(tbl_ReportData[Date])
    )
)

 

This is the prior year measure along with the error I am receiving: 

PY Revenue = CALCULATE([Custom Sales],DATEADD(tbl_ReportData[Date],-365,DAY))

 

Help! 🙂

    Hi dhenders1833 

     

    Try using your date table in the DATEADD.

    PY Revenue = CALCULATE( [Custom Sales], DATEADD( tbl_Date[Date], -365, DAY ) )

      Thanks for the recommendation, however that yields the same error as well.  It will allow me to pull into the visual alone, however when I pull in store number it then errors out.

      Without store #:

        Hi dhenders1833 

         

        Can you replicate this problem with a small sample pbix?   (I've tried a couple of simple examples and mine seem to work as expected.)

         

        Also, can you double-check the error for your most recent example?  The previous error had to do with date tables in particular.
