Comment 21 for bug 717803

i almost forgot to close this bug report and in the meanwhile you had answered, Vadim.

> what is the purpose of grouping the tax lines if their account_account codes are the same?
well, actually the purpose is that: we _need_ a way to group tax line on the invoice, and we need a way generic to do so (on that, we both agree, i think). This way is not worst than another and it's more reliable than using the percentage rate.

i hope this help,
Quentin
