I installed the Service Pack for IC on July 28. We had an inventory item that had the correct cost and pricing on Aug 3. On Aug 4, a CN was enterred in OE for qty 1 of that item. Then the cost went completely haywire. Instead of adding the cost back to the item at $309.26, it added the cost back at $30,926.00. I've never seen anything like this. I've attached screen shots.

DataCare ran every day that week and there were no errors and no repairs. I also checked our Inventory account in Ledger and it increased for the correct amount on Aug 4.

To fix it I suppose I'll have to post a cost adjustment in inventory to correct the item, then delete the batch from ledger. Any idea how this could have happened?
