Function DAX To parameter

Hello,

I have a DAX function that returns the minimum and maximum date of a list of dates

 

Date_Init = CALCULATE(MIN(filters_1[Date]), ALLSELECTED(filters_1))
Date_End = CALCULATE(MAX(filters_1[Date]), ALLSELECTED(filters_1))

 

But when I want to bind a parameter to those functions, the Power Bi app doesn't give me the option to do so.

Is there a way to bind those DAX functions to parameters? Is there another way to do it?

Hi @spmivilsoftbi ,

 

May I know how you want to bind these function to your parameters? What kind of parameters do you want to bind?

If you define your parameter by New Parameter feature, you could directly use it to do calculation. If your parameter is defined in Power Query Editor(Transform data), you could load it to your model and use it to some calculations in your formula or take it to make a visual just like other fields.

And normally, if you would like to take your parameter value into your formula, you could use SELECTEDVALUE/MAX/MIN in measure or directly use the field name of the parameter in Calculated column. So you could make a little bit change to your formulas like this.

 

Date_Init = CALCULATE(MIN(filters_1[Date]), FILTER( ALLSELECTED(filters_1),'filters_1'[column name]=SELECTEDVALUE(Your parameter name)))

Date_End = CALCULATE(MAX(filters_1[Date]), FILTER( ALLSELECTED(filters_1), 'filters_1'[column name]=SELECTEDVALUE(Your parameter name)))

 

 

Here are the official document about these funcitons.

MIN function (DAX) - DAX | Microsoft Docs

MAX function (DAX) - DAX | Microsoft Docs

You cannot use DAX measures as Power Query parameters. You could determine the values in PQ and use them in a different table.

 

 

let
    Source = filters_1,
    MinValue = Table.Min(Source,"Date"),
    Result = MinValue[Date]
in
    Result

Table.Max - PowerQuery M | Microsoft Docs
