Hi All
I found this code, in :addons/sales_order_dates/models/sale_order.py
And changed the below code to "False" from "True" as I thought it was allow me to be able to change the Date once the sales order is done. It doesn't work; Any way to do this? The only module I found was for odoo 8.0
'requested_date': fields.datetime('Requested Date', readonly=False, states={'draft': [('readonly', False)], 'sent': [('readonly', False)]}, copy=False)
