Understanding Sequence of Events
The sequence of events (SOE) is one of the essential techniques of process definition in JD Edwards EnterpriseOne Demand Flow Manufacturing. It defines the work and quality criteria that are required to build a product in a specific production process. It lists the flow of tasks that are required to produce a product according to its product and process design specifications. The sequence of events drives the operational definition and is the basis for all work, line design, and mixed model planning, as well as the operation sheet design.
You define a sequence of events with all the tasks that it contains for every process that is included in the product synchronization for a specific product. The system provides you with the following tools to simplify and streamline the sequence-of-events definition:
Standard tasks.
Standard sequence of events (SSOE).
The use of these tools is optional; however, they can be useful if the production processes contain standard tasks that are used in multiple processes and if you have products that share several work steps that could be defined in an SSOE.
Before you create an SOE or SSOE, you can define tasks that you have identified as standard tasks using the DFM Task Master program (PF30L005). Tasks may include the following information: task name and description, resource type, default times required for setup, move, and work performed by labor and machine resources. After you have defined the task, you assign resources to the task. You can also define Total Quality Control (TQC) criteria for every task. When you add a previously defined task to an SOE or SSOE, you can modify the times for the specific SOE or SSOE.
If you manufacture products that have shared production processes, you use the Standard Sequence of Events program (PF30L110) to define standard sequences of events for those processes. The advantage of a standard sequence of events is that you can reuse it for multiple products because you do not associate it with a specific product.
You create the actual sequence of events for a process and product using the Sequence of Events program (PF30L115). The system provides you with three methods for creating a sequence of events for a product:
Set up the sequence of events and manually attach the required tasks.
Copy a standard sequence of events into the new sequence of events.
Copy an existing sequence of events from an associated item.
You can create a sequence of events by manually attaching the required task information, or you can copy a standard sequence of events into a sequence of events. After you have copied the SSOE to the SOE, you can modify the information in the Sequence of Events program. To copy an existing sequence of events, you select an associated item that has a similar sequence of events. After you have associated this item with the sequence of events, the system retrieves that item's sequence of events and copies it into the new sequence of events.
When you associate tasks with an SSOE or SOE, you can select predefined standard tasks from the FF30L005 table, or you can add nonstandard tasks in the Sequence of Events program or the Standard Sequence Events program. Nonstandard tasks do not have a task name. When you save tasks to the SOE or SSOE, they are stored in the F30L005 table with the standard task property set to N. After creating an SSOE or SOE, you can resequence tasks, for example, when you want to insert a new task in the existing sequence.
As you add tasks to an SSOE or SOE, the system automatically calculates total labor and machine time. The calculation takes into account any overlap that is defined between tasks. The system stores the calculated labor and machine time totals for each process in the FF30L117 table.
When you associate tasks with the sequence of events that you are defining, the Sequence of Events program enables you to associate the components that are consumed by a task with that task. You create the association by selecting the component item number from the product's bill of material. The system stores the association in the FF30L116 table. If you change the task sequence, the components move with the task. If you copy a sequence of events, the system copies only those components that exist on the bill of material of the sequence of events to which you copy the information. If a component does not exist, you have to add it manually afterwards.
When you have completed a sequence of events, you can print the results in the Sequence of Events report (RF30L115). If you create a standard sequence of events, you can generate the Standard Sequence of Events - Print report (RF30L110).
