Hello,

I am using Odoo V16 Online Enterprise in Germany.

I am currently unable to apply a global discount to any order in the Point of Sale (PoS) system. The error log indicates an issue related to a specific module for the German accounting. This error has prevented me from applying a global discount, and I've had to apply discounts to individual products instead. I encountered a similar problem with discount coupons. This resulted in unsynchronized orders remaining in the local PoS session, which cannot be recovered afterward.

Here is the error log: 

TaxError: The tax for the product 'Discount' with id 2 is not allowed.
