Hi,

SQL

SELECT 
	TableA_1.ItemId 
FROM
	dbo.TableA TableA_1
	INNER JOIN dbo.TableA TableA_2 ON
		TableA_1.ItemId = TableA_2.ItemId
		AND TableA_1.SupplierId <> TableA_2.SupplierID 

--This should only give you the duplicated ItemId with different SupplierId, if you only want the duplicated ItemId, remove the last condition.

Hope it helps.
