To ensure that occasional data changes in staging are also present in production for custom objects, the correct approach is to set the custom object definition in staging as Replicable. This setting allows the custom object to be replicated or copied from the staging environment to the production environment, ensuring that any changes made in staging are effectively transferred to production. In Salesforce B2C Commerce, replication is used to synchronize environments and maintain consistency, especially for setups where staging serves as the testing ground before deployment to production.
