sp_helpmergesubscription is used in merge replication to return subscription information stored at the Publisher or republishing Subscriber.

For anonymous subscriptions, the subscription_typevalue is always 1 (pull). However, you must execute sp_helpmergepullsubscription at the Subscriber for information on anonymous subscriptions.

Permissions

Only members of the sysadmin fixed server role, the db_owner fixed database role or the publication access list for the publication to which the subscription belongs can execute sp_helpmergesubscription.
