# Steps to reproduce * create two 17% sales taxes. We'll call those taxes `17a` and `17b`. * set rounding method to global * create a SO with the following 2 lines: * Price = `50.4`, Taxes = `17a` * Price = `47.208`, Taxes = `17b` * note that the total tax amount on the SO is `16.59` * confirm and invoice the SO. You should see that the total tax amount on the invoice is `16.60`. The invoice and SO should have the same tax amount. opw-3179228 closes odoo/odoo#120224 X-original-commit: 715d0e269c3d42a5e25f8ddf648d275069354aaa Signed-off-by: Laurent Smet <las@odoo.com> Signed-off-by: Nshimiyimana Serge Séna (sesn) <sesn@odoo.com> Co-authored-by: Laurent Smet <las@odoo.com> Co-authored-by: Yolann Sabaux <yosa@odoo.com>
