Hi, I have been installed tryton DB and started my trytond without “price\_decimal” setting up on my trytond.conf file. So it takes the default value (4 decimal), now I want to change to only 2 but it show me this error when a try to start the server.
> ValueError: The price\_decimal 2 in [product] configuration section is different from the value 4 in ‘ir.configuration’
Thanks in advance…

Normally no because it would mean losing information about already stored price with 4 decimals.
Of course if you know what you are doing, you can still change also the value in `ir.configuration` table in the database.
