I want to create a new report, or even duplicate an existent, but I can't do that. I don't know if I have to create a module or if I can duplicate some file to replicate the same report with other fields. If I try to create or duplicate from Reports section (pe. Sale.Order) I get this error:
Odoo Server Error - Error de Validación
- Create/update: a mandatory field is not set.
- Delete: another model requires the record being deleted. If possible, archive it instead.
Model: ir.actions.report (ir.actions.report), Campo: Model (model)
