I have a Odoo 9 Community and I want to export the taxes (both the percentage and the amount of money), the total paid (or recieved) money and in case that exists the retentions. The reports has to be generated one each three months (already achieve that).

Right now i am using the pivot view mode. On the rows I have the company and on columns I want to have the taxes, the total paid money and the retentions.

Is there any way to add to the columns the tax percentage and retentions?

If that is not possible, how can I take all that fields without taking them from the database?
