Create dynamic measure based on slicer selection

otto-user101 , To achieve your goal of creating a dynamic measure that responds to slicer selections, it's essential to use a disconnected date table for the slicer. This ensures that your measure can respond independently to the slicer selection without being directly tied to the dates in your base table.

Then you can have measures like

Dynamic Measure =
VAR SelectedDate = SELECTEDVALUE(DisconnectedDateTable[Date])
VAR MaxDate = CALCULATE(MAX(BaseTable[Date]), ALL(BaseTable))
RETURN
SWITCH(
TRUE(),
SelectedDate = MaxDate && BaseTable[Identifier] = "Possible", "Possible",
SelectedDate <> MaxDate && NOT CONTAINSSTRING(BaseTable[Identifier], "Scenario"), "All",
BLANK()
)

Hi otto-user101 ,

Please try below steps:
1.below is my test table

 Base Table:

Table:

Table = CALENDAR(FIRSTDATE('Base Table'[Date]),LASTDATE('Base Table'[Date]))

2. create a meausre with below dax formula

Measure =
VAR _a =
    SELECTEDVALUE ( 'Table'[Date] )
VAR _b =
    SELECTEDVALUE ( 'Base Table'[Date] )
VAR _c =
    SELECTEDVALUE ( 'Base Table'[Identifier] )
VAR _result =
    SWITCH (
        TRUE (),
        _a = _b, _c,
        _a <> _b
            && NOT ( CONTAINSSTRING ( _c, "Scenario" ) ), "All",
        BLANK ()
    )
RETURN
    _result

3. add a  table visual with Base Table fields and measure, add a slicer visual with Table field
