I recently discovered a mountain of 0 quantity items that were holding value, both positive and negative.  I have found that they were caused by receipt adjustments occurring after the goods have shipped.  That is fine I can fix those as we do not have a full time purchasing agent.  My question is why when this happens does the most recent cost not reflect the receipt + the adjustment so it doesn't happen again on the next po for the same item.  I have PO/Options set to use most recent cost.  Please see examples below.
