       , hsce_customers C
       , hsce_country O
       , hsce_elim E
       , HSCE_ITEMS I
       , HSCE_MAPPING M
WHERE T.entity_code = N.code
     AND T.customer_code = C.customer_code
     AND C.ICP_CODE = E.ICP_CODE
     AND C.country = O.code
     AND T.ITEMREF_LOCAL = M.ITEM_REF
     and M.PART_NUMBER = I.PART_NUMBERCan anyone point me to where I have gone wrong?
Thanks

I'm getting the duplicate column name on my query as well; however the validate feature in Toad, validated the query. I can select and even try to tune the query. therefore, I don't understand the error.
