About Systems

The software automatically creates a default root process under the PPR Context when entering the application. This root process is a workplan.

It is possible to have several root processes.

This allows you to define several workplans (or item plans) for the same item. You can easily compare the different workplans by switching from one to another. You do that by double-clicking a root process.

This changes the active root process, which the tree frames in blue, and the process structure that is displayed in the grid in the System Editor.

At a lower level of the tree, it is possible to insert new and existing objects. You can create systems, workplans, and operations in Process Planning, Fastener Planning, and Planning Structure.

Workplan, Header workplan, General system, Transfer system, and Transformation system are available in Process Planning, Fastener Planning, and Planning Structure.

In addition, Sink, Source, and Buffer systems are available when you install Process Flow Simulation. For more information, see the Process Flow Simulation User's Guide.

A system holds a group of operations (and possibly subsystems). These correspond to the steps required to realize completely the manufacturing assembly structure. The scope between the system and an item delimits this manufacturing assembly structure.

Each operation contributes to the realization of one or more child items related to the item dedicated to the system.

The figure below illustrates how you can link a General operation under a System to a Manufacturing Assembly "Assemble (A+B)." You can do this if there is a scope defined between the system and item.

Root processes can be created under the PPR Context using Add > New.

Under Add > Content, the Process Plan and Production System section of the New Content dialog box lists the available root process types.

If you right-click a process type, the Set attributes at creation command allows you to specify (explicit mode) or not (implicit mode) the attributes of the process. User Preferences stores this information.

In addition, you can define the administrator as the implicit/explicit creation mode for each type.

When creating a new process in explicit mode, the attributes dialog box of the process appears. See Creating Systems with Explicit Attributes.

When the creation mode for the process type is implicit, the attributes dialog box does not appear, and the creation mode creates the system directly. The application uses Implicit creation mode when entering with the creation of a root process.

For more information about the New Content dialog box, see 3DEXPERIENCE Native Apps: Working on Objects: Creating Objects.

B.I. Essentials color codes the object tiles and the objects in the tree according to their configuration effectivity status. To compute the configuration effectivity status, B.I. Essentials takes into account processes and operations.

The Configuration Effectivity menu option in the B.I. Essentials panel contains the following information:

Color	Information
Yellow	The effectivity meets the evolution requirements.
Blue	The effectivity meets the variants requirements.
Green	The effectivity meets both the evolution and the variants requirements.
Pink	The effectivity contains nonvalidated change criteria.
White	There is no effectivity.
