Hello,

I created a product for travel expenses, "Travel", with type "Service", procurement method "from order", supply method "produce", default UoM "km", which is how it is explained here:

http://doc.openerp.com/v6.0/book/4/4_11 ... l-expenses

Now, adding this product as a line into an order and confirming it gives the following error:

"Conversion from Product UoM km to Default UoM Day(s) is not possible as they both belong to different Category!."

Which is logical, because it is a service, which requires it to have UoM convertible to UoM type "Working Time", for instance "Day(s)". However, "Travel" does not need to be produced, bought or otherwise be created or stocked.

I tried setting it to type "Consumable", but this creates a delivery order for the travel, which is wrong.

I also tried setting the supply method to "Buy", product type "Service", which kind of works, but creates a procurement order with state "exception", because no supplier is defined. This also seems wrong.

What's the right way to do it? I don't want to use the HR expenses module, because I have to include the estimated travel costs already in the quotations and orders, and not in the invoices at the end. It basically needs to stay Service, from order, produce, UoM km/distance, but with suppressed procurement actions.

Regards, Alex
