Apply visual level interactions without a relationship

Good morning JonPBNES 

As is typical, turns out we were over thinking it.  We didn't need USERELATIONSHIP, we can just read the date range selected, feed that to our filter measure and go.  We do still need to compare Start Date and End Date to the date range.

OpenCaseFilter = 
VAR CompareStartDate = FIRSTDATE ( OpenCasesTable[Date] )
VAR CompareEndDate = LASTDATE ( OpenCasesTable[Date] )
RETURN
    IF (
        CALCULATE (
            COUNTROWS ( 'openfiltertest' ),
            FILTER (
                 openfiltertest,
                'openfiltertest'[Start Date] <= CompareEndDate
                    && 'openfiltertest'[End Date] >= CompareStartDate
            )
        ) >= 1,
        "In",
        "Out"
    )

You can see the result we want even after I deleted the link between the two tables.
