I suspect that it is the inclusion of "purch.Prod_Code" in the GROUP BY clause that is causing the problem.

This:
(case when purch.Prod_Code = 'SP-20.2' then sum(purch.qty) else 0 end) as "SP-20.2",

May be rewritten as:
SUM(DECODE(PURCH.PROD_CODE,'SP-20.2',PURCH.QTY,0)) AS "SP-20.2" By making similar changes to the other columns that are returned, you would be able to remove "purch.Prod_Code" from the GROUP BY clause.
