The HAVING clause is designed as a 'where' alternative for aggregate values. Possibly you should change this to read as follows:

 select purpmt.suppl_code as "Supplier",  sum(purch.qty * purch.unit_price) "Total Purchases"  from purch, purpmt , purinv
 where to_char(purinv.inv_date,'mm') < '07'  and to_char(purinv.inv_date,'yy') = '06'  and (purch.qty * purch.unit_price) > 2000000  and purinv.suppl_code = purpmt.suppl_code  group by purpmt.suppl_code
 order by purpmt.suppl_code;

I expect you'll see different, and more accurate, results.
