I was trying out the accounting, purchase and inventory modules (Odoo 9.0) when I encountered an Issue with validating a vendor bill for a purchase order similar to the one posted here:
The vendor I used in the PO has its account payable field set to "Current Liabilities" type
I solved my issue by following Morten Schou's answer. (Sorry, I cannot up-vote or comment since I do not have enough Karma points yet.)
I created a new account with a "Payable" type, and used it in the vendor's account payable field.
My question now is: Why can't I use a current liability account in a vendor's account payable field?
[If other account types are really not allowed on that field, then there should be a validation that should happen when a vendor record is being saved]
