Considerations for Feature Management

Keep these considerations in mind when working with feature parameters.

After a feature parameter is included in a promoted and released package version, we recommend that you only edit the value field located in LMO-to-subscriber junction objects.

Modifying or deleting other fields or records related to feature parameters, including the data flow direction, may cause the FMA to stop operating correctly.
Don’t use the LMO to create or delete feature parameters.
When you update LMO-to-subscriber values in your LMO, the values in your subscribers’ orgs are updated asynchronously. This process can take several minutes.
When you publish a push upgrade to your managed package, feature parameters in your LMO and your subscribers’ orgs are updated asynchronously. Creating and updating the junction object records can take several minutes.
When the Apex code in your package updates subscriber-to-LMO values in your subscriber’s org, the changes can take up to 24 hours to reach your LMO.
