Hi,

I am using Odoo Online (SaaS~18.4 Enterprise).

I duplicated the default invoice report because I want to customize its header and footer, but I want to keep the same invoice table content as the default report.

The issue is:

• If I edit the header in web.external_layout_standard or web.external_layout_invoice, it changes for all reports (not only my duplicated one).
• I only want the header/footer change to apply to my duplicated invoice report.

My requirement:

• Keep the default invoice table content exactly as it is.
• Use a different header and footer for my duplicated invoice report without affecting other reports.

What is the correct way to inherit the default invoice report content and apply a custom header/footer only for my new report in Odoo Online?

Thanks in advance!
