Does PPR picks up Discouted Invoices

Hello All,

I  have  a problem with the discounted Invoices when running the PPR ..

Scenario :

Invoice Entered Say with 20-JUL-2015

Terms : 0.65 %9 NET 30

GL Date : 20-JUL-2015

terms Date :20-JUL-2015

In scheduled Payments  Tab : I see  Due Date :19-AUG-2015 with Gross amount and FIRST discount :43.59 ( which is correct )

The invoice is Validated and Accounted . Trying to make an Payment Through PPR .

Pay through Date : 20-JUL-2015  - 31-JUL-2015

So I expect the PPR to pick my Discounted Invoice ?? ( 43.59 ) But its completing with PPR - CANCELLED NO INVOICES SELECTED ??

Why is that ?? I wanted to get Discount for that Invoice  actually ?? Is something Wrong ? I tried Multiple times in various combinations but its still showing
