Data labels creation issue

Hi, markzuev6 

Based on your description, I created the following dataset:

The relationship between them is as follows:

Based on the expression you provided, you want to find the current [Dynamic GRP] as a percentage of the current year (clearing 'Dynamic variables (TopN)' [Player type] and Data [Channel group]). 

Create a measure using the following DAX expression:

Measure = ROUND(
    DIVIDE(
        [Dynamic GRP],
        CALCULATE(
            [Dynamic GRP],
            ALLSELECTED('Dynamic variables (TopN)'[Player Type]),
            ALLSELECTED(Data[Channel Group]),
            VALUES(Data[Year])
        )
    )*100 , 0
)/100

The visual settings are as follows:

If you still have any doubts, you can clarify and clearly describe your expected results in the follow-up along with examples.
