# Use LMO-to-Subscriber Feature Parameters to Enable and Disable Features

Feature parameters with a data flow direction value of `LMO to Subscriber` are writable at your end and read-only in your subscriber’s org. These feature parameters serve as permissions or limits. Use LMO-to-subscriber feature parameters to enable or disable new features or to control how many of a given resource your subscriber can use. Or, enable features for a limited trial period. Assign values to LMO-to-subscriber feature parameters by updating junction object records in your LMO, and then check those values in your code.

- **[Assign Override Values in Your LMO](https://developer.salesforce.com/docs/platform/pkg2-dev/guide/fma-assign-override-values.md)**


    To override the default value of a feature parameter in a subscriber’s org, update the appropriate junction object record in your LMO.

- **[Check LMO-to-Subscriber Values in Your Code](https://developer.salesforce.com/docs/platform/pkg2-dev/guide/pd-fma-check-lmo-to-subscriber-values.md)**


    You can reference feature parameters in your code, just like you’d reference any other custom object.
