I have a customer using Apps 10 Update 14. 

I’ve noticed when a part’s cost changes in part_cost_history, the rowversion in inventory_part_unit_cost_tab is not updated.  This means that the cost can change in that table without the rowversion reflecting that it’s been changed.  Is this intended functionality or a bug?

Small test:

Create part and give it an initial unit cost on 10/2

Change the cost on 10/3

Notice that the rowversion still says 10/2 although the cost is now updated.
