Filter a parameter on a materialization dataset

Hello,
I have an object which I transform somehow creating new columns and so on. With this transformations I create a materialization dataset, which I am not able to filter with a parameter. What I want is to have one column of this materialization dataset as a parameter to later on being able to filter with it. The nearest I go through it was transforming the materialization dataset with “Transform table” and being able to filter but only by primary key value of the table.
Any help is welcome. Thanks in advance

Hi Sebastik,

Welcome to the Palantir Developer Community! From your post, it’s hard to tell if you’re using a PySpark code repo, a TypeScript functions repo, or Pipeline Builder. Could you please provide a screenshot (preferably) or more details on the tools you’re using and an example that illustrates your use case?

Thanks!

What I had:

And later on to apply a filter though a String but the options of the column are not set as in the other filters I have.
What I want:

The nearer I go through it was to use “Transform table”

Otherwise, this object type I am able to do it.

This is the data I want to filter with a variable and I can not.

Thanks in advance
