[Bug 707923] Re: [6.0 and 5] invoice tax - rounding issue
Hi,
we are refactoring the module 'account_invoice_tax_by_column' [1] ,
making it dependent from 'c2c_account_tax_rounding' [2] .
This is because account_invoice_tax_by_column is too bound to Italian
VAT: most code introduced by account_invoice_tax_by_column is of use to
Italian computations.
For every standard case (but I didn't test enough with children taxes),
I would suggest to use c2c_account_tax_rounding and follow the way
started by that module: avoid intermediate roundings.
Ferdinand, for c2c_account_tax_rounding, maybe you want to take a look
at automated tests [3] that we are introducing in
account_invoice_tax_by_column

Title:
[6.0 and 5] invoice tax - rounding issue
Status in OpenERP Addons (modules):
Won't Fix
Bug description:
see attachment
due to rounding of the calculated tax for each position we get totals
which are wrong.
In Austria we usually group the basis per tax rate and calculate the
tax from this basis to avoid such errors.
in account/invoice.py
class account_invoice_tax -
def compute must be modified
actually only some lines of code to group the invoice lines before
calculating the tax
probably this has been discussed (but not solved) already
