set_superset_source
This procedure is set to be called from the on-prem HCI database server.
We need to sync product_superset from on-prem to cloud, but db snapshots cannot be replicated to cloud.
To get around this, a snapshot replication has been setup for both product_superset_00 and product_superset_01 and a call to this stored procedure will
create a backup of the superset that is in use on the on-prem database and restore it as [product_superset].
It triples the amount of data, but ensure that the sl2007 db uses the correct data.
