SUM() is not an iterator because it does not own the right to set the DAX engine into row context mode (One of the 2 contexts a DAX expression is evaluated under even though either or both of them can be empty). This type of context is most often applied to the measure rows. Pass those filters along to the Fact table 5. However, DISTINCTCOUNT is better in that case.

In MS-Excel we are all familiar with the drop-down list to choose only items that are required. Basically how many items did we sell in a given time period vs how many cancelled in that same period. Thus, you will use the Cumulative Total pattern only when you can dynamically calculate in a DAX expression the product unit price for any given day.
