+    The report_footer field already existed before, but it only represented the 'extra'
+    text that was added after the company data (https://github.com/odoo/odoo/blob/cc0060e889603eb2e47fa44a8a22a70d7d784185/addons/web/views/report_templates.xml#L367).
+    Now in v15 this data https://github.com/odoo/odoo/blob/3a28e5b0adbb36bdb1155a6854cdfbe4e7f9b187/addons/web/views/report_templates.xml#L338
+    is not shown unless it is defined; therefore, we must apply the corresponding
+    default that would be defined from the base.document.layout wizard and then add the
+    old report_footer data (if it was defined).
+    There is now a company_details field that does not have a default value, so it will
+    be created empty.
+    It is important to define the corresponding value that would be defined from the
+    base.document.layout wizard because in the report now only the content of that
+    field is shown, while in v14 it was not necessary since the address was shown
+    according to the partner_id field.
