NetSales by a date in Column

[NL-Nicolas]

Hey all!

I have a calculated column here:
Last Week = CALCULATE(sum(DayfileSummary[DF_BusinessDay]), FILTER(ALL(DayfileSummary[DF_BusinessDay]),DayfileSummary[DF_BusinessDay]=max(DayfileSummary[DF_BusinessDay])-366))
and when I go to attach it to my field DayfileSummary[NetSales] it will not filter in anyway.

My end goal is to filter the number in each row for the column NetSales by the date in the column DayfileSummary[Last Week]

It is a Year over Year change analyisis for the same day one year ago. In this case Last week is finding their last day on the same fiscal calendar. When I try quick calculate, I cannot use

Update: My column with a date is a measured column. It seems it cannot be used however and my Data has been imported from SQL I feel like I have hit a wall on Power Bi functions here on accident. Help!

Hi @NL-Nicolas ,

I think you can try code as below to catch the same day one year ago based on [Last Week].

DATE(YEAR(MAX('DayfileSummary'[Last Week])-1 ),MONTH(MAX('DayfileSummary'[Last Week]) ),DAY(MAX('DayfileSummary'[Last Week])))

Please share a sample file without sensitive data with me. This will make it easier for me to find the solution.

Here is the error I received from that. I also tried 

Last Week Sales = COUNTX(filter(DayfileSummary, DayfileSummary[NetSales]),DayfileSummary[Last Week])

But it returns nothing! Really stumped on this one

Hey RicoZhou!

Thanks for the response, it turns out my client's DataImport was only 4 months of data! So even if I have been getting the formula right this whole time there was no data to show! I will get back to this post soon after my call today to import the data. I appreciate you trying to help!
