In this pr: https://github.com/odoo/enterprise/pull/30853 we've merged two settings into one to make Tax calculation & display more coherent. In the case of a "Tax per line" computation, the column "Tax Included" is optional=hide in the backend, but we've elected to put it in the PDF all the time. This task we will only change the pdf and portal (preview): 1. Remove the "Tax Incl" column on all relevant templates (pdf/portal). 2. Rename the "Tax Excl" column to "Amount". task-3552656 closes odoo/odoo#138624 Related: odoo/enterprise#48923 Signed-off-by: Florian Gilbert (flg) <flg@odoo.com>
