Error with SAMEPERIODLASTYEAR: an invalid numeric representation of a date value was encountered

I have created a metric to calculate the sales for last year.

Below is the formula:

LastYear_Sales = CALCULATE(SUM('Fact_Sales'[SALES_AMT]),SAMEPERIODLASTYEAR('Dim_Day'[Date]))

 

when I create a table with: Date from Dim_Day and LastYear_Sales, I get the following error:

@vanessa,

 

Based on my test, this can be caused by an invalid datetime value that exceeds the year 9999.

I encountered the same issue when working with SAMEPERIODLASTYEAR. It seems like the date table needs to be Marked As Date Table. This did the trick for me.

Seems like it does not like your [Date] column. Is it flagged as a numeric field in the data model?

I checked that. It is a date/time field.

 

Hmm, reading the error more closely, it says MdxScript, is this a Live data source? (DirectQuery)

 

That function is not supported in DirectQuery mode.

I am using Import mode to fetch data from MySQL.

Could please share the sample data?

 

It would be helpful to assist.
