R30835 Frozen Cost Update - Ledger Entries Not Matching

Hoping someone out there might have a suggestion for me.

In June 2012 my company hired a consultant to do a Frozen Cost Update (Cost Roll), when this was done the processing option for WIP Revaluation (R30837) was not selected, this of course meant that all open work orders were not updated with the new cost. This caused work orders to post to the ledger at the old cost, creating variances between my item ledger and account ledger.

This was not brought to my attention until a few weeks ago. I have been researching and trying to find out what happened. Now that I believe that the update that was run earlier this year is part of the problem, I'm tasked with correcting the problem.
