Exploding BOM through recursive CTE

Hi Guys,

I'm trying to explode the BOM through recursive CTE, but I'm still getting the anchor rows only. However, I'm trying to use this SQL code:

With BOMTree_CTE

AS

(

--Anchor

Select 

B.BOMID

,B.ITEMID 

,B.LINENUM

,B.position

,B.BOMQTY

,B.INVENTDIMID

,0 as 'CurrentLevel'

,BV.BOMID as BVBomId

,BV.ITEMID 

FROM BOM B Left Join BomVersion BV On B.ItemID = BV.ItemId

Union All

Select 

BB.BOMID

,BB.ITEMID

,BB.LINENUM

,BB.position

,BB.BOMQTY

,BB.INVENTDIMID

,CurrentLevel+1

,CAST('1' as nvarchar(20)) 

,CAST('2' as nvarchar(20))

From Bom BB  Join BOMTree_CTE C On BB.BOMID = C.BVBomId

)

select * from BOMTree_CTE C 

I don't wanna do it through X++, I need it through SQL!

Any help is highly appreciated!
