[16.0] sale_order_invoicing_picking_filter Invoiced field readonly?

[ai-landoo]

module: sale_order_invoicing_picking_filter
version: 16.0

The field "Invoiced" in the "Additional Info" tab in pickings shows whether the products in the stock picking have been invoiced. This field is automatically updated. However, it can manually be set to True or False.

If I set it manually to True without that picking beeing invoiced, I can't select it in the invoicing wizard but if I don't select any of the pickings, it will be invoiced.

If I set it manualy to False and that picking is invoiced, I will be able to select it again in the invoicing wizard, but once everything is invoiced in that SO, IT will still detect I can invoice that order as I have invoiced more than I have delivered, and it will create a credit note.

I think the field "Invoiced" in the "Additional Info" should be "readonly".

Despite that I think the module is great! Thank you in advanced!
