Hi all,

I would like to enable the field 'allow proforma invoice' in  the accounting settings, but when I validate I have a constraint error:

Constraint Error : The name of the period must be unique per company!

I saw that you may need to clear all of the period data, but I don't like to as I'm using the accounting.

Maybe we can modify the flag directly in the db ? where ? is it safe ?

For information : Version 8.0-20150225

Thanks for your help

Yannick
