Метод MakePullSubscriptionWellKnown может вызываться только членами sysadmin предопределенных ролей сервера на издателе, членами db_owner предопределенных ролей базы данных в базе данных публикации или пользователями в списке доступа к публикации (PAL).

Вызов MakePullSubscriptionWellKnown эквивалентен выполнению sp_addsubscription для подписки по запросу.
