You have a Power BI model that contains the following two tables:
- Assets (AssetID, AssetName, Purchase_DateID, Value)
- Date (DateID, Date, Month, Week, Year)
The tables have a relationship. Date is marked as a date table in the Power BI model.
You need to create a measure to calculate the percentage that the total assets value increased
since one year ago.
Which DAX formula should you use?
(sum(Assets[Value]) "" CALCULATE(sum(Assets[Value]),
SAMEPERIODLASTYEAR("˜Date'[Date])))/CALCULATE(sum(Assets[Value])),
SAMEPERIODLASTYEAR("˜Date'[Date])))
CALCULATE(sum(Assets[Value]), SAMEPERIODLASTYEAR("˜Date'[Date]))/ (sum(Assets[Value])
CALCULATE(sum(Assets[Value]),DATESYTD(("˜Date'[Date]))/ (sum(Assets[Value])
(sum(Assets[Value]) "" CALCULATE(sum(Assets[Value]),
SAMEPERIODLASTYEAR("˜Date'[Date]))/
matrix
In a Table we will not have empty lines formatting for Year column.
This is an example of a marix visualization.
Create a new table that has columns for the date, year, week, and day.
"and that you can drill down to see ProductName by week and day..."
(sum(Assets[Value]) "" CALCULATE(sum(Assets[Value]),
SAMEPERIODLASTYEAR("˜Date'[Date])))/CALCULATE(sum(Assets[Value])),
SAMEPERIODLASTYEAR("˜Date'[Date])))
