Odoo 11E: Setting a default analytic account
I wish to track my sales budget, which should be relatively straight forward in an ERP but seems difficult in Odoo. So I create a budget and an analytical account called "Revenue". I don't want the staff to have to set an analytical account every time they raise an invoice (1000s of transactions), so how do I set a default analytical account for all sales orders or invoices to the "revenue" analytical account?
I'd prefer to be able to compare a budget to the accounting entries and do away with analytical accounting all together, but since Odoo doesn't seem to be able to facilitate this like normal accounting packages.
