how to create a slicer based on measure

[oakfootballclub]

Hi experts, I want to create a rank measure, the rank is based on ytd amount and ordered descending,

here is the measure I created: 

RANK(DENSE,ALLSELECTED(fact[gpn])  ,ORDERBY([cal_ytd],DESC),,,)

I also want to make the rank as a slicer, I created a column use the same code, but it signs run out of memory even I filtered raw data.

do you have a solution to create such a top x slicer? for example, when I select 50, the following table or matrix show ranked 1 to 50.

Thank you.

@oakfootballclub , You can use TOPN for That

Calculate([cal_ytd], keepfilter(TOPN(50, ALLSELECTED(fact[gpn]), [cal_ytd], desc) ) )

You can replace 50 with a selectedvalue in the slicer. You can also use the WIndow function for the same
