      SELECT 

       [Sell-to Customer No_]
      ,[Bill-to Name]
      ,[Order Date]
      ,[Amount]
     ,[Original Order No_]

     FROM [TBW_BI].[dbo].[Dreams$Internet Orders]
     WHERE [Country]='RUSSIA' and 
     [order date] >= '2016-11-18T00:00:00.000' AND 
     [order date] <= '2017-04-10T00:00:00.000'

try this

Select [Sell-to Customer No_]
,SUM([Amount])
,COUNT([Original Order No_])
