Single Instancing with EV 10.0.3

HI All,

I am new to Enterprise Vault 10.0.3.I have set sharing within a Group.How can I ensure Single Instancing is working ?

I ran below query on SQL, but there was no result.

SELECT VaultStoreIdentity, SharingLevel, IsNull(SUM(TotalLogicalSISParts),0) AS TotalArchivedItems, IsNull(SUM(TotalStoredSISParts),0) AS TotalSharableParts,

IsNull(SUM(TotalLogicalOrignalSize),0) AS TotalOrignalSize,

IsNull(SUM(TotalActualCompressedSize),0) AS TotalCompressedSize

FROM view_StorageReport_SharingType

GROUP BY VaultStoreIdentity, SharingLevel

Best Regards,
