Create Customer numbers automatically
We migrated from an old accounting system to Odoo. The old system automatically created customer number.
We imported those customers numbers into the default code/internal reference of Odoo.
I am using Odoo v9 Online so I can't make a module. Is there a way with a server action that I can do this?
I don't want it to wipe out any customer numbers that are currently applied. I just want the next number in sequence each time a customer is created. So something like: If customer number is blank run server action to create customer number at the next sequence number .
