Hi @marcster_uk - As per my knowledge TOTALYTD takes a literal string as year-end date and it is not possible to enter a dynamic value. I have tried myself and I can’t put dynamic value.
Best option is to use a different dax function other than TOTALYTD. Do let me know if you find any option to make it dynamic.
Would it not be possible to do something similar to what Ankit suggests, and add a column to the date table for Fiscal Year, Operations Year etc, and use the normal calculate pattern where you capture the selected value of the Operations Year and the date, and then the filters in calculate would be date is less than the selected date, and the operations year equals the selected operations year, or use dates between using the current date and the min date for the current operations date to place the filter.
