Cumulative total and limit number of displayed items on a visual

[Anonymous]

Hello,

I am working on a stock management dashboard and cannot figure out how to do the following.

Initial data:

I have a big table on a server with available product stock data for 2020 02 01 data (it shows initial remaining stock for each product for 2020 02 01 date).

This table also contains all sales and purchase data, where sales is a negative number and purchase is a positive number. 

This allows me to see what is the stock situation for certain date (by summing initial stock and sales/purchase operations).

What I need to do:

I want to make a Matrix visual which showed stock situation for last 7 days (in columns) by product (in rows). 

My best guess so far is:

CurrentStock = 
VAR lDate = CALCULATE(LASTDATE(Stock[Date]);ALL(Stock[Quantity]))
RETURN
IF(SELECTEDVALUE(Stock[Date])>lDate;BLANK();
    CALCULATE([TotalQuantity];
        FILTER(ALLSELECTED(Stock[Date]);
            Stock[Date] <=MAX(Stock[Date]))))

If fails to show value on each of the dates. Some dates are blanks (when there are no product movements). Also I cannot find a solution to display only 7 last days in columns.

If someone has any suggestions I would be grateful.

Join it with date table and then try to do it something like this

Cumm Sales = CALCULATE(SUM(Sales[Sales Amount]),filter(date,date[date] <=maxx(date,date[date])))

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :
