DATEADD -1 QTR returns blank values with monthly level fact table if I select only QTRs from Dates

[plukacsi]

 Dear All,

I have a really annoying problem. I have made the usual (Sales Prev.Quarter =
CALCULATE (
[Total Sales_2017],DATEADD(Dates[Date],-3,MONTH))

fuction and gives me blank if I change the filter context in the matrix to Quarter level from monthly level. If I put all the dates from dates table (daily level) and this measure connected to monthly level fact table then I get correct -3 Month numbers monthly, but 

If put only Quarters from date table than normal Total Sales sums up but Sales Prev.Quarter returns blank exept the total row.

Thank you for your help in advance!

BR,

Peter

Hi @plukacsi,

Instead of using the Date_2[DateKey] column and fRedBox_ALL_BG[Month&Year] to built the relationship between the two tables, you'll need to two Date Type columns to create the relationship.

So you can firstly use the formula below add a new calculate column in fRedBox_ALL_BG table.

Date = DATE(fRedBox_ALL_BG[Year],fRedBox_ALL_BG[Month],1)

Then create the relationship with  Date_2[Date] column and fRedBox_ALL_BG[Date].

And the [Sales Prev.Quarter] measure will work as expected.

Here is the modified pbix file for your reference.

Hi @plukacsi,

According to your description above, I have created a measure below, and it works fine at Quarter level.

Sales Prev.Quarter = CALCULATE([Total Sales],DATEADD('Date'[Date],-3,MONTH))

Could you share a dummy pbix file which can reproduce the issue, so that we can further assist on it? You can upload it to OneDrive or Dropbox and post the link here. Do mask sensitive data before uploading.
