Let's see how the Odoo scheduler computes the delivery date. Procurement creates the manufacturing order and the manufacturing start date is computed.
Assume that the routes set on the Computer Desk are Manufacture and Make to Order. The Deadline Start date on the manufacturing order will be computed by the scheduler based on the Manufacturing Lead time. The delivery date is computed based on the Customer Lead Time, and the Vendor Lead time is used to compute the reception date for the incoming shipment.
The Customer Lead Time is set to 15 days, and the Manufacturer Lead Time is set to four days on Computer Desk. Look at the following screenshot of product configuration:
Let's assume that there is a sales order created and confirmed. The sales order Configuration Date is August 11, 2017. The next screenshot shows the sales order:
The delivery date will be computed based on Customer Lead Time. It will be set to August 26, 2017:
The procurement computes the Deadline Start field in the manufacturing order. It will be computed based on the Manufacturer Lead Time. The manufacturing order should start at least four days before the delivery date:
The manufacturing order Deadline Start is set to August 22, 2017. The manufacturing has to be planned for the production based on the assembly line and work center's capacity, and the working schedule. Click on the PLAN button; it will be assigned a scheduling date by which the production will be started and finished:
However, if you would like to change the planning of jobs in assembly, it can be done using the Gantt chart production order or work center. Planning by Production can be accessed by going to Planning | Planning by Production under the Manufacturing application:
The work order can be planned by dragging and dropping the work order in the Gantt view. Planning can be done based on the capacity of the work centers. The working time is attached to the work center. The following is a screenshot of the work center:
The capacity of the work center can be increased or decreased by changing the working time in Working Schedule, the work centers will be working depending on the working schedule:
Scheduling is done by the Odoo scheduler, while planning of the manufacturing can be done by the work center or manufacturing order.
