+You should have at least one template with Default field set, if you choose a Partner the template is deselected as a Default one.
+If you create a new template with the same configuration (Model, Domain, Position) and set it as Default, the previous one will be deselected as a default one.
+
+The template is a html field which will be rendered just like a mail template, so you can use variables like ${object}, ${user}, ${ctx} to add dynamic content.
+
+Change the report related to the model from configuration and add a statement like:
+
+<p t-if="o.get_comment_template('before_lines', o.company_id.id, o.partner_id and o.partner_id.id or False)">
+
+    <span t-raw="o.get_comment_template('before_lines', o.company_id.id, o.partner_id and o.partner_id.id or False)"/>
+
+</p>
+
+<p t-if="o.get_comment_template('after_lines', o.company_id.id, o.partner_id and o.partner_id.id or False)">
+
+    <span t-raw="o.get_comment_template('after_lines', o.company_id.id, o.partner_id and o.partner_id.id or False)"/>
+
+</p>
+
+You should always use t-if since the method returns False if no template is found.
