Update Item Cost Entry Point
This process changes your historical item costing data to per Item&Variant&Location after you upgrade from 3.x and 4.x to 5.0.
As of this release, the upgrade toolkit automatically changes your Avg. Cost Calc. Type to Item, irregardless of what you set before.
It's possible that MSFT will release a patch to address this, but in the mean time, this will hold you over.
You will need to run the adjust cost process after this is done; which will take a while.
