PLs, is there a standard way to use fields in related objects to display them in ONE VIEW? E.g. I'd like to extend the basic account.invoice.tree view by a field from account.move.line (e.g. "name" = write-off), so that I know, if an invoice is paid, and write-off was applied on it. I am stuck in xml.... (base_report_creator in v7.0?)

Any information is more than welcome!!!! Thank you very much in advance!
