# Parameter download support for reference set assignment

Download and edit parameters to devices using reference set assignments inherited from the device hierarchy in the Device Profile screen.

## What is reference set parameter download support?

This feature supports downloading parameters to devices whose assignment type is a reference set — assigned either directly to the device or inherited from the hierarchy.

The *Device Profile* screen displays the reference set name assigned to a device. With a reference set assignment, you can edit parameters directly on the *Device Profile* screen.

{% hint style="info" %}

* No parameter upgrade support is provided for parameters inherited through reference sets.
* No parameter template support is provided at the reference set level.
  {% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.verifone.com/support-us/verifone-hq/vhq-parameter-management/configuring-parameter-templates/parameter-download-support-for-reference-set-assignment.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
