Personal Custom App

[chochobo78]

Hi everyone, I'm new to this community and for fun I like studying programming languages, etc. I'm not an expert, but I can manage my way around. I'm studying Odoo 18 CE and I've created a custom app to manage purchase discounts.

The app allows the user to create discount codes and internally calculates the final discount based on 10 discount fields (e.g., discount 1 + discount 2 + discount 3 = applicable discount). This discount is then loaded into the Purchasing section under the supplier.

The app works, but I'm having a lot of trouble adding the call to the function (and opening the related page).
Is there a way—and if so, how—to add this menu item under the Purchases | Products section?
