Lookup Tables utilize a "Table and Revision" model, which lets you update data cleanly, and extend the schema without modifying existing calculations: * Create Revisions for a Lookup Table, which you can use to define data schema and lookup keys. * Populate draft Revisions with data values. You can create and edit multiple draft Revisions, but only one can be published at any given time. * Publish a Revision to activate it. When you use Lookup functions in your calculations that reference the Lookup Table, the data values defined for the published Revision are used. * When you want different, updated data values to be used, publish the draft Revision containing the required new values. The currently published Revision is archived automatically. **Beta Version!** The Lookup Table feature is currently available in Beta release version. See [Feature Release Stages](/guides/getting-started/feature-release-stages) for Beta release definition. Lookup Table Revision endpoints will only be available if Lookup Tables have been enabled for your Organization. For more details see [Lookup Tables (Beta)](/guides/lookup-tables) in our main User documentation.
