Data Archive issue in 8.8 - Inventory Valuation Tool

Trying to archive a DB in 8.8, however when I select the period I want to archive to it displays error "WARNING: You cannot run data archiving without first running the Inventory Valuation Utility"

I have searched hi and low on the forums here, and elsewhere with absolutely no info on the inventory valuation tool to be found anywhere.

Anyone have any info regarding this at all.
