Scheduled dates are computed in order to be able to plan deliveries, receptions and so on. Depending on the habits of your company, Odoo automatically generates scheduled dates via the scheduler. The Odoo scheduler computes everything per line, whether it's a manufacturing order, a delivery order, a sale order, etc. The dates that are computed are dependent on the different leads times configured in Odoo.
Configuring lead times
Configuring lead times is an essential move in order to compute scheduled dates. Lead times are the delays (in term of delivery, manufacturing, ...) promised to your different partners and/or clients. Configuration of the different lead times are made as follows:
On a product level
Supplier lead time:
The supplier lead time is the time needed for the supplier to deliver your purchased product. To configure the Supplier lead time select a product (from the Purchase module, go to), and go in the Inventory tab. You will have to add a Vendor to your product in order to select a supplier lead time.
It is possible to add more than one vendor per product and thus different delivery lead times depending on the vendor.
Once a vendor is selected, click on it to open its form and indicate its delivery lead time.
In this case security days have no influence, the scheduled delivery days will be equal to: Date of the purchase order + Delivery Lead Time.
Customer lead time
The customer lead time is the time needed to get your product from your store/warehouse to your customer. It can be configured for any product. Simply select a product (from the Sales module, go to), and go into the Sales tab to indicate your customer lead time.
On the company level
On company level, it is possible to parameter security days in order to cope with eventual delays and to be sure to meet your engagements. The idea is to subtract backup days from the computed scheduled date in case of delays.
Sales Safety days
Sales Safety days are back-up days to ensure you will be able to deliver your clients engagements on time. They are margins of errors for delivery lead times. Security days are the same logic as the early wristwatch, in order to arrive on time. The idea is to subtract the numbers of security days from the calculation and thus to compute a scheduled date earlier than the one you promised to your client. That way you are sure to be able to keep your commitment.
To set up your security dates, go to the app, and click on Configure your company data.
Go the Configuration tab to indicate the number of safety days
Note that you can in this menu configure a default Manufacturing lead time.
Purchase days response to the same logic than sales security days.
They are margins of error for vendor lead times. When the system generates purchase orders for procuring products, they will be scheduled in order to cope with unexpected vendor delays. Purchase lead time can be found in the same menu as the sales safety days (see screenshot above).
On route level
The internal transfers due to the movement of stocks can also influence the computed date.
The delays due to internal transfers can be specified in the Inventory module when creating a new push rule for a new route.
Read the documentation What is a push rule? to learn more.
On document level:
Odoo offers the possibility to indicate a requested date by the client straight on the sale order, under the tab Other information. If this date is earlier than the theoretically computed date, Odoo will automatically display a warning.
As an example, you may sell a car today (January 1st), that is purchased on order, and you promise to deliver your customer within 20 days (January 20). In such a scenario, the scheduler may trigger the following events, based on your configuration:
- January 19: actual scheduled delivery (1 day of Sales Safety days)
- January 18: receive the product from your supplier (1 day of Purchase days)
- January 10: deadline to order at your supplier (9 days of supplier delivery lead time)
- January 8: trigger a purchase request to your purchase team, since the team needs on average 2 days to find the right supplier and order.
