Hope it helps

Hello, 

In Odoo 16, the thousands separator defined in the language settings is generally used for number formatting, but some views and widgets may rely on localization rules or client-side formatting that do not immediately reflect changes made in the language configuration.

A few things worth checking:

• Clear browser cache and reload assets after modifying the language settings.
• Verify whether the issue occurs in all modules/views or only in specific fields.
• Confirm that the user is actually using the pt_PT language and not another Portuguese variant.
• Check whether any localization or custom modules are overriding the default formatting behavior.

If the issue persists in standard Odoo without customizations, it may be related to the localization implementation for pt_PT in Odoo 16 and could require further investigation.

Hope this works for you! If you need any help implementing this or want a more optimized approach, feel free to reach out for further discussion.

Hello Kunjan Patel,

Thank you. Your solution worked perfectly. Setting Separator Format = [3,0] fixed the issue.
