Invoice tax base computing differ from untaxed amount

[Paulius Sladkevičius @ hbee]

This bug reproduced on the 6.1, but I think its same on the Trunk.

Issue is that invoice tax base calculation don't apply rounding for unit price * quantity, but counting invoice untaxed amount subtotal is rounded.

Please look to http://bazaar.launchpad.net/~openerp/openobject-addons/trunk/view/head:/account/account_invoice.py#L1607. I see that for tax['price_unit'] not needed rounding, mainly it's needed to round val['base'] = tax['price_unit'] * line['quantity'].

Untaxed amount is calculated with sum of invoice line subtotals.

Later will attach screenshot to see how that tax base differ from untaxed amount.

Hello Ravish,

strange that you don't reproduce this problem. Can be related with 986300 bug.

But mainly if you look from logical side, how untaxed amount is computed and how tax base, you will see that it's done in 2 different ways, so please look from this side.

Hello,
I have seen the same problem in OpenERP 6.1: for some invoices, base amount may differ from untaxed amount. Please have a look to the attachment.
