Hello,

The Sales Analysis (sale.report) is a custom report based on an SQL view.

Adding new fields to it requires modifying the Python code, which unfortunately isn’t possible on SaaS.

You can refer to the following documentation for more details:

Dear Zuhair,

In Odoo Studio, to add the "Effective Date" field to your view:

2. Scroll down and expand the "Existing Fields" section.
3. Search for "Effective Date" in the list of fields.
4. Drag and drop the "Effective Date" field to the desired location on your form.
