Hi,
How I can add 2 values in a RML report, I need do something like:
Account invoice report in table line get the result of (amount_total - residual), I try lambda, but doesn't work, and I don't really understand how its works.
Thanks for help me.
<para style="terp_default_8">[[repeatIn(getLines(o), 'line') ]]</para>
<blockTable colWidths="80.0,100.0,100.0" style="Table3">
<tr>
<td>
<para style="terp_default_Centre_9">[[ formatLang(line['date_due'],date=True) or '' ]]</para>
</td>
<td>
<para style="terp_default_Right_9">[[ company.currency_id.symbol ]] [[ formatLang(line['amount_total']) ]] </para>
</td>
<td>
<para style="terp_default_Right_9">
[[ formatLang((reduce(lambda x, y: x['amount_total']) - (y['residual']), 0))) ]]
</para>
</td>
</tr>
</blockTable>
