# Import historical data

Microsoft stores up to 13 months of billing data. To perform a billing reimport in FinOps for Cloud:

1. Navigate to the **Data sources** page.
2. Select the Azure data source, then select **Billing reimport**.
3. In **Import from**, choose the start date of your historical billing data.
4. Select **Schedule import**.

Once the import process has been initiated, it might take several hours for the process to complete, depending on the amount of historical data.

{% hint style="info" %}
A billing reimport can only be started on individual Azure subscriptions. This functionality is not available to the parent tenant.
{% 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.finops.softwareone.com/system/data-sources/microsoft-azure/import-historical-data.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.
