Percentage difference measure

Hi gbarr12345 ,

Ritaf1983 Thanks for your concern about this case!
And gbarr12345 , the problem should be with these two measures of yours:

Here I build a sample data myself:

Measures:

Depletion First 12 Months = 
CALCULATE(
    SUM('Table'[Depletion]),
    ALL('Table'),
    MONTH('Table'[Date]) >= 1 && MONTH('Table'[Date]) <= 12 && 'Table'[Year] IN VALUES('Table'[Year])
)

Exports First 12 Months = 
CALCULATE(
    SUM('Table'[Exports]),
    ALL('Table'),
    MONTH('Table'[Date]) >= 1 && MONTH('Table'[Date]) <= 12 && 'Table'[Year] IN VALUES('Table'[Year])
)

Year 1 % difference = 
VAR Dep = [Depletion First 12 Months]
VAR Exports = [Exports First 12 Months]
RETURN
IF(
    Exports <> 0,
    DIVIDE(Dep, Exports, 0),
    BLANK()
)

And the final output is as below:

If there is still a problem, could you please provide your sample data, and the DAX you created for these two measures, please!

Best Regards,
Dino Tao
