SQL Server Database Engine
Snapshot failed to process publication '%s'. Possibly due to active schema change activity or new articles being added.
This error is raised if the Snapshot Agent starts running when there are ongoing changes to the publication database, including adding or dropping articles and performing schema changes on published objects.
Restart the Snapshot Agent after changes to the publication database are complete. For more information, see Start and Stop a Replication Agent (SQL Server Management Studio) and Replication Agent Executables Concepts.
