Currently, we are experiencing an issue with the sales validation process On Odoo 14. Here's how the process works:

1. Sales are generated from four different branches and synced to the main database.
2. A scheduled action is set to validate the sales every evening. However, during the daytime, there is another sync scheduled action running.
3. The validation scheduled action is responsible for validating the sales, confirming them, and delivering the products. We follow a policy where an invoice is created and validated after the delivery.
4. To perform these actions, we utilize action buttons on the sales quotation, sales order, delivery, and invoice.
5. We employ real-time inventory valuation, which means a valuation is created for each sale.

The problem we are currently facing is that the validation process is taking a significant amount of time. On average, we are able to validate fewer than 700 sales per night, while we have a backlog of approximately 130,951 sales that still need validation.
