LASTDATE issues
I have a date table ('Date Table'[Date]) connected to a date column of irregular start dates ('Table'[Date]).
For example, the irregular start dates could be:
1/31/2017
4/30/2017
8/31/2017
If I make an active relationship between 'Date Table'[Date] and 'Table'[Date], I run into this issue:
I am using a date slicer on 'Date Table[Date]' to select an "as of" date to run the report for. I want LASTDATE('Date Table'[Date]) to return the last date selected on the slicer. However, because of the relationship with 'Table,' it will instead only return one of the values 1/31/2017, 4/30/2017, or 8/31/2017.
The goal of the LASTDATE function is to implement the test: "is the selected date on the slicer on or after the start date for this column? Return TRUE or FALSE"
How do I get around this but keep the relationship active?

What's the full measure you are using?
And keep in mind that LASTDATE is a table function which will transition a row context to a filter context....so having said that, you may want to use MAX ( 'Date Table'[Date] ) instead.
For all intents and purposes, the full measure is just LASTDATE('Date Table'[Date]), which in this case returns the same thing as MAX()
If I have my date slicer set for all dates on or before 9/30/2017, you would expect LASTDATE() to return 9/30/2017 on the date table.
However, in this case, it returns 8/31/2017 because it is last date that appears.
I should note that I am using a calculated column rather than a measure.
can you share your measures/calc column and sample data, and also relationship model. it will help to debug
