Dynamic Measure Title Based on Slicer Selection

Hi, safrik 

Based on your description, I created data to reproduce your scenario. The pbix file is attached in the end.

Table:

Calendar(a calculated table):

Calendar = 
ADDCOLUMNS(
    CALENDARAUTO(),
    "YearMonth",
    YEAR([Date])*100+MONTH([Date])
)

YM(a calculated table):

YM = DISTINCT('Calendar'[YearMonth])

Relationship:

You may create a measure like below.

Result = 
var yearmonth = MAX(YM[YearMonth])
var lastym = 
    CALCULATE(
        MAX('Calendar'[YearMonth]),
        FILTER(
            ALL('Calendar'),
            [YearMonth]<yearmonth
        )
    )
return
IF(
        MAX('Calendar'[YearMonth]) in {yearmonth,lastym},
        SUM('Table'[Amount])
)

Finally you need to use 'YearMonth' column from 'YM' table to filter the result and set the 'Result' as not blank.

Best Regards

Allan
