Matrix returns all combinations

[nospang]

Hi all,

I want to display value 'X' for a means to indicate the current month (will serve as a today line). In the screenshot the yellow part should contain the value 'X'.  The names that are used are coming from the dimensions. 

However when creating measure below, the matrix return all possible combinations:

 How do I only display the relevant rows?

For further reference, screenshots of the model and tables

The bridge table links all the tables to each other

Hi @nospang ,

I suggest you to try code as below to create a measure.

today line =
VAR _CurrentMonth =
    DATE ( YEAR ( TODAY () ), MONTH ( TODAY () ), 1 )
VAR _CheckIfCurrentMonth =
    MIN ( 'Calendar'[Date] ) = _CurrentMonth
VAR _Result =
    SWITCH ( TRUE (), _CheckIfCurrentMonth, "X", BLANK () )
VAR _Lev2List =
    CALCULATETABLE (
        VALUES ( bridge[Lvl2ID] ),
        FILTER ( ALL ( bridge ), bridge[Lvl1ID] = MAX ( 'Level 1'[ID] ) )
    )
RETURN
    IF ( MAX ( 'Level 2'[ID] ) IN _Lev2List, _Result )

Result is as below.
