Thanks Dhivya, but it's not exactly what I want. Maybe is my comprehension of Odoo that is wrong. I would like to know if it is possible to reset to 0 the "Profit (Loss) to report" when I generate a balance sheet after the last day of my fiscal year. Normally, in other accounting appllications, we generate a balance sheet only by specifying a date (we don't have to specify a date range including a start date). With Odoo, I think I need to specify a start date from my new fiscal year to generate my balance sheet with 0 as "Profit (Loss) to report". Does I'm right? If I have to specify a start date when I generate my balance sheet, I will have to create a journal entry at the first day of my new fiscal year with all account balances coming from last year. Does I'm right?
