Running "Scheduled Payment Selection Report" as a Request

I have a question about running the Payables R12 report "Scheduled Payment Selection Report" as a concurrent request.

Normally, this report request gets kicked off, or submitted, automatically when a payment process request (PPR) is created.  When the PPR creation kicks off the "Scheduled Payment Selection Report", the report is good -- it shows payment data.

But if I submit the "Scheduled Payment Selection Report" myself as a concurrent request for an existing PPR, the report shows no payment data.  Is this normal?  Am I not supposed to be submitting the "Scheduled Payment Selection Report" myself manually?

FYI - In my most recent test, I ran the "Scheduled Payment Selection Report" manually for a PPR that was created and processed 2 days ago.  I will attach the manually-submitted report with no payment data.
