Comentários

Calling AddMergeDynamicSnapshotJob is equivalent to executing sp_adddynamicsnapshot_job.

The AddMergeDynamicSnapshotJob method can only be called by members of the sysadmin fixed server role at the Publisher or by members of the db_owner fixed database role on the publication database.
