3rd Item Number Issue

We somehow have two different 3rd item numbers for a handful of items in at least the F4102, F4105, and F30026 tables.  Is there a standard UBE that can run and update the 3rd item number across multiple files?  I looked under Advanced Inventory in the Global Updates and Purge and don't see anything there that looks like it will update the AITM.  I remember that there at least used to be a UBE that would update the LITM and accessed a UDC to determine the files to be updated, but I can't find it.

Thanks,

Jeff
