when the last purchase price was updated in the location tab, the system is still displaying the old

Hello,

I am having difficulties to understand why the system doesn't update the "Last Purchase price" under the Purchase/Inventory section, even though the field is updated in the inventory subtab for each location.

Also, when I update the default cost in the inventory subtab for each location, run the rollup up and the revaluation, still, for the items that don't have any quantity on hand, the system doesn't seem to update the "Last Purchase price" in the inventory tab for every location.

Would you please bring some light?

Thanks
