HI @panipat1990,

I think you are talk about query parameter which create in query editor, right?

If this is a case, current query parameter can setting dynamic list from other query, but it not support setting dynamic value based on above list.

For your requirement, I'd like to suggest you direct use #"query name"['column name'] with list.max function to get dynamic value, then use it in filter steps.

Assuming that your data is in SQL, you could create a view that would result in a 4months to date data, you could then import that on to powerBI and then setup a scheduled refresh job everyday.

Hi @panipat1990

You can apply a filter by clicking the button at the end of a column header of your date column (as per (1)) and then choose a Date Filter that suits.

But i want to data only maxdate. How is it possible through parameter.

[Phil_Seamark]

So do you mean a dynamic range of dates?  eg, always the 4 months relative to the current date?

[panipat1990]

Yes Current date to last 4 month's data dynamic

I created a blank query and used the following M code and named it dateParam

let
    Source = Date.From(Date.AddMonths(DateTime.From(Date.StartOfMonth(DateTimeZone.FixedUtcNow())),-4))
in
    Source

This generated a single value of 1/12/2017  (d/MM/yyyy)

I then edited my main table to incorporate this parameter in a filter

    #"Filtered Rows" = Table.SelectRows(#"Changed Type1", each [Date] > dateParam)

I've attached a simple model to show it working.
