- If the Meter has multiple External mappings created for it, you can use _Search external mappings_ to search by **External table** and **External entity ID** and filter the list.
- You can commence a workflow to **Create external mapping** for the Meter directly - see [Creating and Managing External Mappings for Accounts](https://docs.m3ter.com/guides/end-customer-accounts/creating-and-managing-external-mappings-for-accounts) for an example.

**Integration runs**. If you’ve set up an integration that synchronizes the Meter with an external system, the date/time and status of the **Latest** integration run are shown. You can use a text hotlink to open details of this latest run or **View all runs**. See [Reviewing Integration Run Details](https://docs.m3ter.com/guides/integrations/setting-up-integrations/reviewing-integration-run-details).
