Create a custom measure that totals "total demand" for 7 days

Summary:

Want to create a custom measure that sums the "total demand" for a total of 7 days from the next day to the next 7 days.

Content (required):

I created a custom measure with the expression "Fsum(Total Demand,7)" to achieve the above objective, but it does not work as expected.

　■Requirement

　➡Measure on 7/11: contains values for 7 days from 7/12~7/18

　➡The calculation has been completed for each weekly bucket.

　　Measure on 7/17:value from tomorrow through the weekend is in.
