Effective Date of Item

Hello,

I'm currently getting an error on an order. For some products, new unit price values as Effective date of item ​​were defined for the customer price group at 01/10/2024.  The order was submitted on 27/09/2024 but the G/L date appears to be 02/10/2024.

Here, is the date and value of the valid unit price based on the order entry date or the accounting date?

Could someone give me any answer please? I'd be so glad. Thank you.
