Also, the same applies for situations when you receive 1 invoice for multiple receipts. The same Combined Inv/Adj function on the header works for combining receipts for the same vendor into a single invoice.
You might think that multiple receipts generating a single invoice doesn't happen very often, but when used with the receipt error correction process (ie. negative quick receipts), you will quickly find the combine Inv/adj (for combining receipts) easily matches up to the vendor's invoice, without having to do manual inventory cost and quantity adjustments.
