Hoping to get some help here on an issue I have never seen.
Typically, I use SAMEPERIODLASTYEAR and setup a specific calendar table for all my Power BI reports. No issues with any other report but this one I am currently working on.
This issue creates errors across the entire report, but it can be distilled down to when I run the SAMEPERIODLASTYEAR calcuation (on a date such as 3/23/2020), it returns the end of the month of the previous year (3/31/2019), instead of my desired date (3/23/2019).
The below screenshot is what is occurring. My calendar table currently has not relationships to any other tables.
