Running total over snapshots

Hi

I have a fact table where each month a snapshot is taken from our production system. The result is a format which looks like the following when pivoted. I also have a ‘ReportingFinancialYearText’ field which tells me which financial year it is when the snapshot it taken. In the pivot below it is 2016/2017 when the 2017May snapshot was taken and is 2017/2018 when the 2017Sep snapshot was taken

I have created a YTDActuals measure which calculates the running total for the financial year. This works as expected.

YTDActuals:=TOTALYTD([Sum of Actuals],DimDate[Date], ALL(DimDate[Date]), "6/30")

I am now trying to create a currentYTDActuals measure which shows the YTDActuals measure but only for the relevant financial year as dictated by the ‘ReportingFinancialYearText’ field. I have tried to just filter down the YTD actuals measure however this seems to remove the running total element. I have included the desired result below.

CurrentYTDActuals:=
CALCULATE(
	[YTDActuals],
	FILTER(
		Fact_Financials,
		Fact_Financials[FiscalYearText] = Fact_Financials[ReportingFinancialYearText]
	)
)

Any ideas what I am doing wrong?

Many thanks!
