Payment control groups - discounts

Hello,

We are using OneWorld XE and I have following problem launching the R04570 (Payment control groups) for vouchers with discounts,

How can I setup a payment control group to

1/ include vouchers whose net due date  (RPDDJ) has not been passed: invoice amount less discount

2/ include vouchers whose net due dateRPDDJ and discount due date RPDDNJ  have been passed : invoice amount

3/ exclude vouchers whose net due date RPDDJ has been passed, but the discount due date RPDDNJ has not been passed

When I have run the R04570, I don't succeed in excluding the 3/ vouchers.

Regards

Katrien
