Hello, I wanted to know how to apply perceptions automatically and have them appear on the sales invoice.
In Argentina we have perceptions of Gross Income (IIBB - Ingresos Brutos en Argentina) of each province. Which we would like a label that the client has to appear according to, entering the contact, then Fiscal Data and IIBB (gross income), in it it will be put that they are multilateral because they can be associated with many provinces.

Then we enter accounting and in the created tax we put the following values
Name of the tax = Perception IIBB CABA Applied
Tax calculation = Aliquot in the Partner

The issue that the sales invoice does not appear when I select the customer and start adding the lines of the invoices, the tax does not appear. It only allows you to select it in the tax column. I would like to know if this has a solution in the Odoo 14 version or in later versions?
