When setting up a subscription, you can specify that SQL Server will synchronize the published articles with the destination tables, and that the synchronization will repeat at defined intervals. Inserts, updates, deletes, or modifications to the published data will not be provided to the subscribers. This is called a Scheduled Table Refresh. In effect, it is a repeating automatic synchronization, with replication of subsequent transactions turned off.
For example, a scheduled table refresh could be useful if you need to completely refresh the data on a particular subscriber once a day, once a week, or once a month.
