Hi Eliza,

In Odoo's stock.picking model, the "Late" and "Is Late" filters are used to filter records based on the delivery date of a picking.
The "Late" filter is used to filter all pickings that have a delivery date before the current date, meaning they are already overdue for delivery. This filter is used to quickly identify all pickings that are late, regardless of how late they are.

The "Is Late" filter, on the other hand, is used to filter only the pickings that have a delivery date that is past the expected delivery date by a certain number of days. This filter is used to identify pickings that are specifically late by a defined period.

In summary, the Late filter shows all pickings that are past due, while the Is Late filter shows only the pickings that are specifically late based on a defined period.
