If the Item has a valuation of Standard then the values you see in Average Cost if informational only.

I agree from a pure accounting standpoint, these numbers are not used for anything.  But the tables are incorrect, and currently hold numbers that are huge.  Average costs into the billions of dollars.  It looks weird when one views an item in inquiry and if we try to utilize these fields in a crystal report nothing will match.  Informational or not, Sage should have a fix to make the table correct.

Is there any utility that I can run to correct these fields?

If you ship before receipts (making a negative on hand quantity) this value becomes corrupted.
