Hi,

Yes, it's possible to extend dynamic reports like the balance sheet in Odoo's Accounting module by adding additional columns from another module. This can be done by customizing the report's template and logic. You would typically inherit the existing report template, add the new columns to the QWeb template, and then modify the corresponding Python methods that generate the report data to include fields from the other module. This allows you to display additional information in the report.

Hope this helps.
