Replication Server uses a maintenance user login name for each local data server database that contains replicated tables. Replication Server uses this login to maintain replicated tables.
The Database Administrator must make sure that the maintenance user login name has the permissions needed to update the replicated tables in the database.
Normally, transactions applied by the maintenance user are filtered by the Replication Agent so they are not replicated out of a database. In certain applications, however, these transactions must be replicated.
