AP Reserve Invoice & Unlinked Goods Receipt

We are running into problems where users are creating AP Reserve Inovoices to pay for products prior to receiving them. Then the users who create the goods receipt are either not copying from the reserve invoice or they are breaking the link when they modify the line items. Now what can we do so we don't have two open documents? Right now we have an amount sitting in the prepaid GL account created from the reserve invoice and an amount sitting in an accrual account created from the open goods receipt. We need to close these against eachother. Any suggestions?

Thanks,

Ryan
