Answer 1

You need replace cte.CategoryId=#newtemp.ParentCategoryId on c.ParentCategoryId = #newtemp.CategoryID

;with cte (rowid,ParentCategoryID,CategoryID,Status,Level,CategoryName,ISProduct) as
 (
  Select  rowid, ParentCategoryID, CategoryID, Status, Level, CategoryName, ISProduct 
  from #newtemp  
  where ParentCategoryId!=0
  union all
  select t.rowid, t.ParentCategoryID, t.CategoryID, t.Status, t.Level, t.CategoryName, t.ISProduct
  from  #newtemp t inner join cte c ON c.ParentCategoryId = t.CategoryID
  )
  select * from cte
