What I am trying to do is this.
table OEINHDIH is history of orders. Orders can have many order type rows. so that order 12345 can have types INT, COR etc within it.
we need the orders which are INT but don't have a correction order against it (COR COE). But when i run this sql i get only 1 ihent#. Also this has to be run in Crystal report where the user will drive this according to dates from and to which is h.IHDOCD.
select h.IHDOCD, h.IHENT#, h.IHSFX#, h.IHINV#, a.ADINTA
from astdta.OEINHDIH h
join astdta.Adressad a
on h.ihent# = a.ADENT#
where h.IHORDT = 'INT'
AND h.IHVIAC not in ('PML','FCM')
AND ADSFX# = '000'
and h.ihent# in (
select cor.ihent#
from astdta.OEINHDIH cor
where cor.IHORDT not in ('COR','COE'))
