Data Flow - Window Transformation - NTILE Expression

Question

I'm attempting to assign quartiles to a numeric source data range as it transits a data flow.

I gather that this can be accomplished by using the ntile expression within a window transform.

I'm failing in my attempt to use the documentation provided here to get any success.

This is just a basic attempt to understand the implementation before using it for real application. I have a numeric value in my source dataset, and I want the values within the range to be spread across 4 buckets and defined as such.

Thanks in advance for any assistance with this.

Hello @Wilson, Chris ,
Thanks for the question and using MS Q&A platform.
As we understand the ask here is how to use Ntile function in sdata flow , please do let us know if its not accurate.
Let me start with the fact that I had never used this function before in data flow and you ask did gave me an oppurtunity to dig into this .
You need to use the 'Window option dataflow and that should do the trick .

You need to set the below fields and it should help .

Mine output looked something like this

Please do let me if you have any queries.
