Inventory summary shows negative receipts for fully posted transactions

This issue was isolated to 3 incidents over a 6 week span and has not recurred for months.  We believe this to have been an unidentified bug from several months ago that appears to have been fixed.  The following SQL scripts were used to correct the perceived data corruption, 1 item/LotSerialNbr at a time.

DECLARE @CompanyID int, @InventoryID int, @LotSerialNbr nvarchar(50);  
SET @CompanyID = 4;
SET @InventoryID = 1401;
Set @LotSerialNbr = 'don'
