"A/P Down Payment Request" Work Arround problem

Question

Hello Experts,
I am getting ptoblem in "A/P Down Payment Request", as the outgoing payment being made against that particular "A/P Down Payment Request" is not shown in "A/P Invoice".
Scenario:
1. I made PO >> (against this PO) I made "A/P Down Payment Request" by using "Copy From" Option.
2. I made an Outgoing Payment against that "A/P Down Payment Request" (...works fine).
3. Now when I make "A/P Invoice" it does not show the "Down Payment" just made, in (down payment option) "Down Payment to Draw", as it is required to NET OFF the A/P amount.
Note: whereas if we do the same above mention procedure with "A/P Down Payment Invoice" instead of "A/P down Payment Request" it works fine and payment will be shown in Down Payment option at A/P Invoice Document.
Help Required ....
Regards

Thank you very much for your reply,
you are right but the problem is that "A/P Down Payment Request" allows me to make a payment against it ....thats fine.
But at the time of making A/P Invoice, at the bottom of the form after Discount Field there is an option "Total Down Payment" and a button to see & select the down payment(s) against that BP.
But it does not show the any payment against the "A/P Down Payment Request" ?
Actually: I would want Purchase department to make the "A/P Down Payment Request" after making the PO so that Finance people can do action on it.
Please comment.....
Regards,
