Why is my DAX measure displaying incorrect values when using time intelligence functions?
I’m working on a Power BI report using time intelligence functions like TOTALYTD, SAMEPERIODLASTYEAR, etc., but the DAX measures are returning incorrect values. The totals or comparisons don’t match expectations, and I suspect the issue lies in how my date table or DAX calculations are structured. What are the best practices for using time intelligence functions in Power BI, and how can I troubleshoot the incorrect values?
