Does anyone know what table/column the LastPurchasePrice showing on the Netsuite UI Item screen is from?

The field help on the item record kind of explains all that.

Are you writing about the help that pops up when you click on the field name? That is like an HTML object label or something. What I'm looking for is the table/column name like table ITEM_LOCATION_MAP, column LAST_PURCHASE_PRICE. By the way, that is not it. that table/column shows every LAST_PURCHASE_PRICE for every DC.
