# Check measure usage
When hovering on any dimension or metric, you can check if it is already used in any reports or question.
Check measure usage
When a metric or a dimension is already in use we will display an arrow next to its name and an alert explaining where it is used. You can still delete it but you should be aware that this cannot be undone and that it might break the reports that are using this measure.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.whaly.io/data-management/explorations/check-measure-usage.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
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.
