Tengo la version 16 online, no encuentro donde personalizar las plantillas el informe z.

you can customize the Z report template.

Here's a general outline of how you can achieve this:

1. Identify the template used for generating the Z report: In Odoo, the Z report is usually generated based on a report template. Find the specific report template used for the Z report in your Odoo installation. You can check the configuration or consult the documentation for your POS module to locate the template.

2. Customize the report template: Once you have identified the report template, you can customize it to display only the desired information. Edit the template file (usually in XML or QWeb format) and modify the structure and content to include only the total product sales and VAT.

3. Remove unnecessary sections: Remove sections or blocks of code from the template that display individual product details, such as the product name, quantity, and price. Keep only the sections that calculate and display the total product sales and VAT.

4. Update the report configuration: Depending on your Odoo version and setup, you may need to update the configuration to associate the customized template with the Z report. Check the documentation or configuration settings for your POS module to ensure the updated template is correctly linked to the Z report.

5. Test and generate the Z report: After customizing the template and updating the configuration, test the Z report generation. Run a session in the Point of Sale module and generate the Z report. Verify that the report now includes only the total product sales and VAT without listing individual products.
