Clear Open Receipts

What is the best way to clean up open receipts that have zero cost on them?  These are receipts for PO items that will never be vouchered and they have no cost associated.  They are mostly from prior years and/or periods that have been closed.  Some of them are for serial items; some are not.  Some are for warranty return items we used to process through the normal PO process as zero cost items.

These open receipts are skewing the RNV reports and also have a small impact on inventory valuation reports.  We would like to get these cleaned up, so they stop showing up on RNVs and Inventory.  Yes, we could use data selection to filter these out, but that only masks the real issue with these transactions that are stuck in limbo.
