Problems with Dates in a measure with USERELATIONSHIP

[sglendenning]

The following measure is being used as the denominator in a calculation but I have a slicer on the page where if I select a value from the slicer I don't want the denominator value to change.  In the table below I always want the denominator to be 6381 regardless if I select either Same Month or Diff Month from the slicer on the page.  This has to be able to work in a table that has more than one month at a time...e.g. it will have each month of 2022 and each month will have different expirations.

CALCULATE(sum(Combined[Units]),USERELATIONSHIP('Date'[Date],Combined[ExpirationDate]))

CalendarYear	Expirations
2022	6381
Feb	6381
Same Month	6199
Diff Month	182

Figured it out;

CALCULATE(sum(Combined[Units]),USERELATIONSHIP('Date'[Date],Combined[ExpirationDate]),ALL(Combined[MONTH BIN]))
