Hi Gilbert,

To add a field like a checkbox to your custom report using Odoo Studio, you can refer to the following resources:

• For Odoo version 16 (V16): You can check out this blog post on Cybrosys for detailed instructions on customizing views and reports using Odoo 16 Studio: 
• How to Customize Views and Reports in Odoo 16 Studio Module
• For Odoo version 17 (V17): Odoo's official documentation provides guidance on adding fields to PDF reports using Studio in Odoo version 17: 
• PDF Reports Customization with Odoo Studio (V17)

Both resources offer valuable insights into customizing reports using Odoo Studio for different versions of Odoo. You can choose the one that corresponds to the version of Odoo you're currently using.

Hope it helps

Can  you show the solution that you got ?

I have found the solution in adding checkbox in the xml

But the problem is as soon as I make a modification of the report studio kill this.

Any solution ?
