On Odoo 8, I have a product "Iron Maiden" with no fields filled in on the Inventory Valuation section of the Inventory tab other than "Inventory Valuation: Real Time (automated)".

It has "Internal Category" set to "All / Goods"., which is configured with:

Stock Input Account: 100110 Goods

Stock Output Account: 529000 Purchases - Resale Items

Stock Valuation Account: 100110 Goods

Income Account: 479100 Sales of Goods

Expense Account: 100120 Goods In Transit

When I make a purchase including "Iron Maiden", the resulting invoice shows the Account as "100110 Goods". I was expecting "100120 Goods In Transit". Why is this, and how can I change the behavior?

I manually changed the account field. Then, when I received the shipment, the resulting journal entries showed transfers from "100110 Goods" to "100110 Goods" (I was expecting "100120 Goods in Transit" to "100110 Goods"). Again I manually changed the entry.

I assume that somewhere, Odoo is misreading the Expense Account value. What can I do?

Note: I have pictures, but I don't know how to upload them
