Note to myself: I think we should change this.

You should change this! for warehouse/purchase employees the order is done after receiving and order delivery, they don't manage payments. Is there a way to adjust the workflow of the purchase orders?

I disagree. From the point of view of the warehouse employees - they can consider the receiving and delivery documents. When they are done, their job is done. A sale/purchase is a legal exchange of goods or services for money. Until the exchange is complete, the SO or PO isn't complete.

I think that Tom is right, from the perspective of the guys receipting the order the work is done. being paid is a separate department and separate flow in my opinion.

I did get round this by adding a button and calling action_done()

I agree with Fabian & Tom - the order is done once the goods are received

I think that the basic problem in my case is that even though i followed the workflow and paid the vendor the status remains in purchase order and does not transfer to done. Looking at the deliver check box on the PO I can see tha it is still unchecked. What is wrong in the default setup of the system and what do I need to change?

Pls explain how to call this action_done(). I created a button, type="action" name="action_done()", but the purchase order status does not change to "Done". What am I missing?

Ok, this happens on our 6 month old installation and I installed the latest version today. I do the following: Create manual PO, confirm PO, receive goods, receive invoice and pay invoice..... yet the PO does not close. So even the standard PO closure routine does not work. This I believe was a bug a while but, which I assumed was fixed. We are close to considering a support contract, but as it stands the basic functionality seems broke for PO's.
