Hi,

We use Odoo 10 CE and wish to have default values based on a condition.  The model in question being Invoice (account.invoice).

In the Invoice model, we have fiscal position ( fiscal_position_id) and journal ( journal_id).  We are able to select the fiscal position of the customer from the partner form and this changes on the Invoice -> other info tab depending on the selected customer.

We wish to select the corresponding journal based on corresponding partner fiscal position. For example, for all partners who are fiscal position as Normal, the corresponding journal on the invoice shall be Sale Journal and for all partners who have fiscal position as Exempt , the corresponding journal on the invoice shall be Invoice Journal.  

Kindly help.

Regards,
