Inventory Revaluation

We have two locations A and B. We bought item X at $2 but erroneously invoiced it at $500. A transfer shipment was done from location A to B. It’s after this that we noted the unit cost error and corrected this using a credit note and re-invoicing at correct value. The transferred qty was consumed from location B through the job module.

The unit cost is showing correctly at $2 and Qty is nil. However we have, a -ve valuation at $500 sitting in location A and a +ve valuation at $500 in location B. Is there a way of correcting this. Remember Qty is nil… NAV 2013
