In practice the DATESYTD function can be replaced by a FILTER, and the previous expression corresponds to the following one: If you know how the filter context (https://www.sqlbi.com/articles/row-context-and-filter-context-in-dax/) works, you might wonder why the filter over a single date column removes the filter on other columns (such as Year and Month), as it happens when you use the measure for year-to-date using the expression above in a report.
