Using a date plus calculation

[Seanhu7]

I have a table that has sales by store by date over a six month period.

Looking for DAX calculation that can when I chose a specific date say 01/12/2019 plus 14, I can get the sum of the sales for the period contained within i.e. 01/12 and the next 14 days

I then want to use this column to report on stores with zero sales during this period

Thanks in advance

Hi,
If you have a date slicer where you can select the date from table DateTable column Date it could be something like this:

Sales14Days =

CALCULATE (SUM(['SalesTable'[Sales]); FILTER (ALL(SalesTable[Date]), SalesTable[Date] >= MAX(DateTable[Date] && SalesTable[Date] <= MAX(Date[Date]) + 14))

If there are no sales the measure will return BLANK().

EDIT: Changed ALL(SalesTable) to ALL(SalesTable[Date]), could perhaps be better, depends on your requirements.

This would be easier if you provided sample data and expected output. Please see this post regarding How to Get Your Question Answered Quickly: https://community.powerbi.com/t5/Community-Blog/How-to-Get-Your-Question-Answered-Quickly/ba-p/38490

That being said, you can simply add 14 to your date. [Date] + 14. So you could do a filter like [Date] >= Specific Date && [Date] <= Specific Date + 14
