thanks MUHAMMAD
by default there is a field named note in account.fiscal.position
and a field named fiscal_position_id in pos.order
how can add this field in the receipt ?
my pos.xml file :
<templates id="template" xml:space="preserve">
<t t-name="OrderReceipt" t-inherit="point_of_sale.OrderReceipt" t-inherit-mode="extension" owl="1">
<xpath expr="//div[@class='pos-receipt-contact']" position="inside">

</xpath>
</t>
</templates>
thanks for helping me

To add the "note" field from the "account.fiscal.position" model and the "fiscal_position_id" field from the "pos.order" model to the receipt, you can use the xpath element to specify where in the template you want to add the fields and then use the field element to define the fields themselves. Here is an example of what that might look like:

Copy code
<templates id="template" xml:space="preserve">
<t t-name="OrderReceipt" t-inherit="point_of_sale.OrderReceipt" t-inherit-mode="extension" owl="1">
<xpath expr="//div[@class='pos-receipt-contact']" position="inside">
<div class="pos-receipt-note">
<span class="pos-receipt-label">Note:</span>
<field name="note" widget="text" options='{"readonly": true}'/>
</div>
<div class="pos-receipt-fiscal-position-id">
<span class="pos-receipt-label">Fiscal Position ID:</span>
<field name="fiscal_position_id" widget="text" options='{"readonly": true}'/>
</div>
</xpath>
</t>
</templates>
You should also check if the fields you want to add are related to the receipt model in odoo.
