Are there any batch jobs that could run over a item location record (F41021) and change the GL Class

We recently had an instance where the GL Class code was changed on an item location records.  There are previous transactions that occurred that occurred under the correct GLC (same GLC as the item master and item branch), but then at some point that specific item/location record was changed to a different GLC.  We have no idea where the value came from and why it updated.  We are fairly certain that it was not a manual change.  Any thoughts on this would be greatly appreciated.
