The Replication Agent filter_maint_userid configuration parameter controls whether the Replication Agent forwards transactions performed by the maintenance user to the primary Replication Server. The maintenance user name is defined in the Replication Server create connection command for the primary database.
In a bidirectional replication environment (replicating both into and out of the same database), set the value of the filter_maint_userid parameter to the default true. If you do not, transactions replicated to another site may return to be applied at the originating site, creating an endless loop.
