Constraint values in multiselect slicer

Hello NourJ,

Create a measure that checks if the selected values in the slicer contain either "A" or "B" and if they do, the measure will remove "D" from the selection. Similarly, if the selected values contain "D", the measure will remove "A" and "B" from the selection.

Selected Values = 
VAR SelectedValues = VALUES(Table[Column])
RETURN
IF (
    CONTAINSSTRING(CONCATENATEX(SelectedValues, Table[Column], ","), "A") 
        || CONTAINSSTRING(CONCATENATEX(SelectedValues, Table[Column], ","), "B"),
    EXCEPT(SelectedValues, VALUES(Table[Column]), VALUES(Table[Column]) = "D"),
    IF (
        CONTAINSSTRING(CONCATENATEX(SelectedValues, Table[Column], ","), "D"),
        EXCEPT(SelectedValues, VALUES(Table[Column]), VALUES(Table[Column]) IN {"A", "B"}),
        SelectedValues
    )
)
