This bug is present in OpenERP 6.1 (not in OpenERP 6.0) with an up-to- date codebase. Here is a detailed scenario to reproduce the bug : 1. Create a new DB with demo data 2. Install the module "account_accountant" 3. Activate "Extended view" 4. Create a new customer invoice for the partner Agrolait in EUR currency Add an invoice line with : - Product = HDD1 (could be any) - Quantity = 100 - Unit price = 0.56 - Discount = 15% (if you have a tax, check that it's NOT a "tax included" one) 5. Click on compute tax : you will see that : * The total untaxed amount of the invoice is 47.60 * At the bottom left, in the invoice tax lines, there is one line ; in this line, the "base" amount is 48.00 ! => These two amounts should be identical ; that's the bug. The cause of the bug is the following : * the "price_subtotal" of the invoice line is computed that way : 1. (quantity * unit price) * (1-discount/100) = 47.60000 (cf line 1272 of account_invoice.py) 2. Round at the precision of the EUR currency = 47.60 (cf line 1277 of account_invoice.py) * but the "base" amount of the invoice tax line is not computed the same way : 1. price_unit * (1-discount / 100) = 0.47600 (cf line 1588 of account_invoice.py) 2. Round at the precision of the EUR currency = 0.48 (cf line 1589 of account_invoice.py) 3. Multiply by the quantity : 0.48 x 100 = 48.0 (cf line 1596 of account_invoice.py) I have written a patch that makes OpenERP compute the "base" amount of invoice tax lines with the same method as the "price_subtotal" of the invoice line. I enclose the patch to this bug report. In fact, this bug was introduced in the branch addons-6.1 by the commit 5569 dated 2011-11-10, cf http://bazaar.launchpad.net/~openerp /openobject-addons/6.1/revision/5569. This commit was designed to fix this bug : https://launchpad.net/bugs/887367. I have tested the scenario of this bug report to see if my code re-introduces this bug ; it's not the case.
