Hi,

To move the "Question Date", "Expiration", and "Salesperson" section to the right of the "Quotation # 00004" heading in an Odoo report (likely a QWeb report), you'll need to modify the report's XML template.

- Locate the QWeb Report Template(sale.report_saleorder_document)

- Inherit the template and make changes in the inherited template.

Add your div or group by using XPath.

<xpath expr="//div[@name='informations_reference']" position="after">
    <!-- Your custom div  here -->
</xpath>

Ensure to upgrade the module.

Hope it helps
