## Accessing business rule versions

To keep track of your business rules, use the **Version** field.

:::note
After you save the business rule with the uploaded DMN file, you can no longer change its version.

You can view the version of a business rule from the **Business Rules** page. To check the version, select a business rule, then either edit the business rule, or go straight to **More Actions**, and select **View versions**.

If needed, you can also download the version of a business rule through one of the following methods:

* Once you upload the DMN file during the business rule creation, select the download icon located next to the file.
* From the **Business Rules** page, on the desired business rule, select **More Actions**, then **Download version**. Alternatively, under **More Actions**, select **View versions**. A side panel opens, where you can select the download icon next to the version you want to download.

## Executing a business rule

:::note
Before you execute a business rule, make sure that:
* You model a DMN file with the help of a [DMN-compliant editor](https://bpmn.uipath.com/).
* You create a new business rule in Orchestrator by uploading the DMN file.
* You have view rights assigned to view the business rules.
* After deployment, the process can access the business rules it uses.
:::

1. To execute a business rule, open UiPath® Studio.
2. Add to your workflow an [Evaluate Business Rule](https://docs.uipath.com/activities/other/latest/workflow/evaluate-business-rule) activity or a **Business Rule Task** process diagram.
3. Use the DMN file stored in Orchestrator in the activity or process diagram.
4. Map input and output arguments according to how the DMN file is modelled.
5. Execute the process directly from Studio, or upload the package to Orchestrator, and execute it from there.
