In this video learn about how to deal with a \u201cSlowly Changing Dimensions\u201d, where the Dimension = Employee and the changing Attribute = Team. See a solution for reporting Teams and Employee Sales Over Time using the Matrix Report. Most Important, see how to take a Team-Employee Lookup Table and 1) Create a Dimension Table using the SELECTCOLUMNS function and 2) Add Team-Employee Key to Fact Table by performing a three-way lookup using the CALCULATE, VALUES and FILTER Functions. See a second way to do the 3-way lookup in DAX with the SELECTCOLUMNS and FILTER Functions.
