Hello,
We plan to update our odoo 12.3 to 15.
I started testing to adapt our processes using xmlrpc.
I saw that the account.invoice model was merged with account.move.
I manage to create the account move as an invoice, but I cannot add lines to this invoice. I'm trying to adapt our old process of creating the account.invoice.line objects next. So I wanted to add an account.move.line but I can't because I get the following error in return:
There was a problem with the following move(s):
- Move with id 68522
Cannot create unbalanced journal entry. The balance is equal to -128,00 €

Could you tell me how I should go about successfully creating an invoice in this version 15 of odoo?
Thanks
