Filter dataset before applying summarize (create new table ) statement

I have a data model in PowerBI which consists of a Fact Table and a dimesnion

For simplicity sake ill call it Fact and Dimension.

Fact:

Dimesnion

The relationship between these 2 tables are dimesnionid on dimensionid

Now I need to create a Summarize statement like the following:

Table =
SUMMARIZE (
    'Fact',

    'Dimension'[Name],
    "Value",SUM('Fact'[Value])

)

Now this seems to work as a once off.

But now when i filter the date on the front end in a filter. The values of the calculated table does not adjust according to the filter.

So ideally I would like a solution where the summarize statement is based on the filtered set of data on the fact and not the full dataset.

So When i filter the datetime on the report. The table must recalculate based on a new subset of Fact Records.

Im stuck.

Please help.
