Group By and Sum for this query in SQL SERVER : I want to group by OrderNumber, Product, ConveyanceID and Trip for this below query and sum(Volume).

How can I do that

    SELECT OD.[Customer]
    		  ,OD.[OrderNumber] 'Order#'
    		  ,OD.[Shipper]
    		  ,OD.[Product]
    		  ,OD.[Dock] 'Dock/Track'
    		  ,OD.[Lines] 'Berth/Position'
    		  ,[TAMS].[fnc_GetDelayCountByOrderNumber](OD.OrderNumber) 'Delays' 
    		  ,OD.[ScheduledArrival] 'Sched .Arrival'
    		  ,OD.ActiveCheckPointStatus 'Active CheckPoint'
    		  ,OD.[CheckPointStatus] 'CheckPoint Status'
    		  ,OD.[ContractNumber]
    		  ,OD.[Direction]
