Hi,

You can refer to the following resources for a detailed understanding of Analytical Accounting:

• Analytical Accounting Odoo 17 Accounting Book :https://www.cybrosys.com/odoo/odoo-books/odoo-17-accounting/configuration/analytical-accounting/
• Analytic Accounts in Odoo 17 Invoicing - https://www.cybrosys.com/odoo/odoo-books/v17-ce/invoicing/analytic-accounts/

Hope it helps

To automatically apply all Analytic Accounts from a selected Analytic Plan in Odoo:

1. Add a field to select the Analytic Plan in your form view.
2. Set up an onchange method on the Analytic Plan field.
3. In that method, fetch all Analytic Accounts linked to the selected plan.
4. Populate those accounts into the corresponding lines (e.g., budget lines or analytic distribution).
5. Optionally, limit the selectable accounts to those related to the chosen plan using a domain.
6. Refresh the form view after selection so users see the updated lines instantly.

This ensures users can apply all related accounts from a plan with a single selection—streamlining data entry.

Hope this works for your case!
