        *
from(

select ItemNumber, des.[Product Family], ItemDescription, des.Country, month(RequestedShipDate) as 'Month', ItemOrderedQuantity
from FS_COLine co
join FS_Item it on co.ItemKey = it.ItemKey
left outer join FIN_PLANCAP_2..ProductDescriptions des on it.ItemNumber collate database_default = des.RICNum
where RequestedShipDate >= convert(datetime, '01/01/2016', 120) and
      RequestedShipDate <= convert(datetime, '12/31/2016', 120) and
    isNumeric(it.ItemNumber) = 1 and 
    isNumeric(des.RICNum) = 1 
   --and it.ItemNumber = 35191305
group by ItemNumber, des.[Product Family], ItemDescription, des.Country, month(RequestedShipDate), ItemOrderedQuantity
order by ItemNumber
