Hi,

You can change the effective date using an Odoo server action. You also need to update the date fields of the related stock moves and stock move lines to match the effective date. Only then will the stock be reflected as processed on the backdated date(2023).

1. Settings->Technical->Actions->Server Actions

Type: Execute Code

Model: Transfer

2. Run the server action on the receipt corresponding to the purchase order by going to Purchase Order -> Receipt ->Action -> Stock Move in Backdate.

After running the server action, you will see that the effective date has been changed to the backdated value.

Stock Move Line

Hope it helps
