DECLARE @Columns as VARCHAR(MAX)
SELECT @Columns =

(select  distinct FT.FeatureName  from #ItemFeatures Feat inner join [CustomerLocations].[ItemFeatures] ItemF
on ItemF.CustomerId=Feat.CustomerId INNER join CustomerLocations.FeatureTypes FT on ItemF.FeatureId=FT.FeatureId

  select F.ItemId,F.ItemId as ItemCode,I.IPN,I.PartnerName,I.PartnerPart,Itm.CustomerName,t.FeatureName,F.FeatureValue,F.FeatureValue as FeatureValues
               from #ItemFeatures Itm 
 inner join [CustomerLocations].[ItemFeatures] F on F.CustomerId=Itm.CustomerId

 inner join CustomerLocations.FeatureTypes T on T.FeatureId=F.FeatureId
