Description:
Whenever we update a module in Odoo, all its XML file gets loaded and updated to the latest version of code available. So we provide a noupdate attribute with the data tag in our XML if we want to avoid updating to any data or code within our XML file (say in the case of sequence number generation). By adding the noupdate attribute further updations to the record becomes restricted while updations. In order to make it possible we'll use the function tag in XML and remove the noupdate value as True, make the updations and make the noupdate value as True again.
