Hi,

To see the actual date instead of the remaining days, we need to remove the 'remaining_days' widget used in the field. To achieve this, inherit the view as follows:

<record id="view_in_invoice_bill_tree_inherited" model="ir.ui.view">
   <field name="name">account.move.view.tree.inherit</field>
   <field name="model">account.move</field>
   <field name="inherit_id" ref="account.view_in_invoice_bill_tree"/>
   <field name="arch" type="xml">
       <xpath expr="//field[@name='invoice_date_due']" position="attributes">
           <attribute name="widget"></attribute>
       </xpath>
   </field>
</record>


Hope it helps.
