Remarks

If there are multiple publications on a database, and any one of those publications uses an infinite publication retention period, running sp_mergemetadataretentioncleanup doesn't clean up the merge replication change tracking metadata for the database. For this reason, use infinite publication retention with caution. To determine if a publication has an infinite retention period, execute sp_helpmergepublication at the Publisher and note any publications in the result set with a value of 0 for retention.

Permissions

Only members of the db_owner fixed database role or users in the publication access list for a published database can execute sp_mergemetadataretentioncleanup.
