Rolling Calculation with Filter

[andy_pat]

I have a rolling sum calculation as my measure. The measure works fine, but the additonal requirement is to hide the last 7 days of calculated data.  The data older than 7 days should show up even if the slicer on Date column is moved around.

See pbix attached here

Moving sum = CALCULATE(SUM(Data[Value]),
                      DATESINPERIOD(Data[Date],LASTDATE(Data[Date]),-7,DAY)
)

 The Grand Total also needs to reflect the correct number, which at the moment is incorrectly showing as 7

Any guidance would be really helpful.

Adding more detail: 

 The dates from 7-26 to 08-01 should return blank value for the measure, when the latest date is 08-01.  The window of blank data should change from 7-27 to 08-02 the latest date changes to 08-02  In other words, trying to blank out the latest 7 days of data.

Part 2: 
The "Total" still shows 7. Need to fix that to reflect the correct value.

Thanks

Andy

@andy_pat , not very clear .The information you have provided is not making the problem clear to me. Can you please explain with an example.

Something like this

Moving sum before 7 days= CALCULATE(SUM(Data[Value]),
                      all(Date)) - CALCULATE(SUM(Data[Value]),
                      DATESINPERIOD(Data[Date],mx(Data[Date]),-7,DAY))

or

7 Day behind Sales = CALCULATE(SUM(Sales[Sales Amount]),dateadd('Date'[Date],-7,Day))

Appreciate your Kudos.

Thanks. I added a scenario in my post.  The goal is to calculate the moving sum for all dates except the last 7 available dates, as the date range advances each day.

@andy_pat , Try measure like these, see if this can help

measure =
var _max = maxx(all(Date), Date[Date])
return
calculate(if(max(Date[Date]) >=_max-7, blank(), [measure])) // you can use 0 in place blank

measure =
var _max = maxx(all(Date), Date[Date])
return
Sumx(values(Date[Date]), if(max(Date[Date]) >=_max-7, blank(), [measure])) // you can use 0 in place blank
