OK, I installed openerp7 and tried to make POS sale, every time i get this error: There is no receivable account defined to make payment
I have a payment method defined and assigned to the main POS with accounts configured .
I found that in version 6.x I have to manually define property_account_payable/receivable but in 7 it's already there.
What should i do to bypass this error ? what config step is missing ?
