What step should be taken to ensure a custom object can be replicated from staging to production?

To ensure a custom object can be replicated from staging to production, it is essential to mark the object as replicable in the staging environment. By creating the object in staging as replicable, you inform the system that this particular custom object should be included in the replication process when you move content and configurations from staging to production. This step is crucial because, without this designation, the object may not be considered for replication, potentially leading to inconsistencies or missing data in the production environment.

In the context of Salesforce Commerce Cloud, replication is a significant process for transitioning configurations and content, ensuring that the development and staging environments align accurately with production once changes are made. By following this specific step, you ensure that the custom object is properly prepared and recognized for the replication process to be effective.
