Remarks
The EnabledMergePublishing property can only be set by members of the sysadmin fixed server role.
The EnabledMergePublishing property can be retrieved by the sysadmin fixed server role on the server, by the db_owner fixed database role on the replication database, and by a user in the public access list (PAL) for a publication published from the replication database.
Setting EnabledMergePublishing is equivalent to executing sp_replicationdboption (Transact-SQL).
Getting EnabledMergePublishing is equivalent to executing sp_helpreplicationdboption (Transact-SQL).
