DAX Function Help

Hello,

My requirement is to calculate max ExtractDate(Column Name) for each month in dataset after filtering the dataset based on user selected report parameter in Power BI Desktop.

For Example:  

Dataset  :

Plant       Component        material     Month      ExtractDate     Forecast

P1              C1                      M1           201601        5-Jan-16          10

P1              C1                      M2           201601        8-Jan-16          15

P2              C1                      M3           201601        10-Jan-16         20

If user select Plant = P1 and Component = C1 and Material = ALL then Max(ExtractDate) should be 8-Jan-16 But I am getting 10-Jan-16

How to calculate Max Date dynamically affter filtering the dataset by user selected parameter.

Thanks in Advance for help. Swift help is appreciated

Regards,
