Accrual Reconcilation Report

I have situation where a PO was matched with Invoice and then the merchandize was returned back to supplier. This showed up on Accrual Reconciliation Report. We later received the merchandize but was not recorded in the system. To resolve this I created a receipt and re-ran accrual reconciliation report that still shows up same balance. I am wondering if someone can provide me correct steps to record supplier return and resolve the issue for the transactions not to show up on accrual reconciliation report.

thanks
