Flow Order
Flow order is a concept used in environments with a more or less continuous flow of material issues and product receipts. Flow order is characterized by planned material issues. In the material plan, product receipts are distributed during the days when an operation is running.
Distribution occurs only in the material plan. Work Center Scheduling shows that the entire quantity of the order should be ready by a certain date.
Before you start
The concept can be used when these prerequisites are met:
- Flow order is activated for product and material in 'Item. Connect Facility' (MMS003). Activation can be set for all or released orders.
- Work centers, used to distribute the planned demand/supply, are defined as flow order resources in 'Work Center. Open' (PDS010).
- A time fence can be specified when flow order is activated.
- Flow orders with a finish date within the time fence are distributed in the material plan
- Material demand with a reservation date within the time fence are distributed in the material plan.
Beyond the time limit, no distribution occurs.
Description
When the order is within the time fence, the planned manufactured quantity is evenly distributed over time the last operation is running, if the operation is a flow order resource. When calculating the quantities to distribute, the quantities are always rounded up, except for the last record. Rounding error is adjusted to the last transaction of the distribution.
Planned demand of the manufacturing order, for materials defined as flow-order planned, is evenly distributed over operation time for the corresponding operation. Adjustments for rounding error is calculated the same way as for planned receipts.
In the material plan, flow order transactions are defined for the product with a sequence number in the field 'Order line'. The sequence number begins at one for the first day's delivery. For the following days, the sequence number increases by one.
Example
This example shows an order with two operations. Operation 020 uses material Y, and 030 uses material Z flow-ordered. Order quantity for the manufacturing order is 629 pieces. No scrap is planned so 629 pieces are planned for operation 020 and 030. Operation 020 start with 100% remaining capacity on the start day and operation 030 starts when 75 % of the capacity remains. The operation time is 3 days in operation 020 and 4 days in operation 030.
This results in the following daily distribution:
Operation 020, lead time 3 work days. One material (Y) per product
