La UseWebSynchronization proprietà può essere recuperata solo dai membri del ruolo predefinito del server sysadmin nel Sottoscrittore o dai membri del ruolo predefinito del database db_owner nel database di sottoscrizione.

La UseWebSynchronization proprietà può essere impostata solo dai membri del ruolo predefinito del server sysadmin nel Sottoscrittore o dai membri del db_owner ruolo predefinito del database nel database di sottoscrizione.

Il recupero della proprietà equivale all'esecuzione UseWebSynchronization di sp_helpmergepullsubscription.

L'impostazione della proprietà equivale all'esecuzione UseWebSynchronization di sp_addmergepullsubscription_agent o sp_changemergepullsubscription.
