In Odoo (Accounting → Configuration → Management → Accounting Reports), report lines have a “Hide if Zero” option.

This works as expected on several financial reports, but does not work on the Aged Payable report.

In Aged Payable:

• Vendors with zero balance still appear

• All period columns (period0 … period5) are zero

• total is zero

• “Hide if Zero” is enabled on the report line

I understand that Aged Payable uses a custom Python engine (_report_custom_engine_aged_payable) and grouping (partner_id, id).

Questions:

1. Is “Hide if Zero” expected to work on Aged Payable?

2. Does the custom engine bypass the standard zero-line filtering?

3. What is the correct way to hide vendors with zero total balance in Aged Payable?

Any clarification on the intended behavior or best practice would be appreciated
