Hi @abubakar

You can [recursively copy](https://forum.alumio.com/t/recursively-copy-values-to-children/287) the root level’s `attributes` object into all the objects of `wProductVariantions` array as `match_attributes`. Then you can use the below [JMESPath](https://forum.alumio.com/t/use-jmespath-to-simplify-your-transformations/189) to filter out all objects that do not match the attributes object copied inside each `wProductVariants` objects.

```auto
&{wProductVariations[?attributes == match_attributes]}

```

Please give it a try and let us know if you have any questions.
