Overview of Phantom Explosion in Work Orders

A phantom represents a product that is physically built but not stocked, before being used in the next stage or level of manufacturing. It is a method to move around a group of components having the same item name. When you create a work definition for a parent product item, you can specify the supply type of a component as phantom. You can define work definitions for phantoms in the same way as any other product items.

During the creation of a work order which references a work definition, the following happens:

• The application selects the appropriate work definition version based on the work definition date specified and explodes the work definition by copying its operations, resources and component items.

• When a component item with phantom supply is required for an operation, the application looks for a work definition for the phantom item, explodes the same by copying its constituent components and resources to the same operation.

• The action of whether only components or both components and resources must be inherited is determined by the plant parameter Phantom Operation Inheritance.

• If multiple levels of phantoms are encountered during the explosion process, the application keeps exploding though all levels until no further child phantoms are encountered.

• At any level, if the explosion process does not find a work definition for a phantom, it uses the item structure to explode that phantom level and its lower levels. If an item structure is also not defined for a phantom item, further explosion is not performed for that node.

Note:

Phantom assemblies act like normal assemblies when they represent a top-level assembly, such as when you create a work order on it. However, as a subassembly, they lose their identity as distinct assemblies, and are a collection of their components and resources.

Note:

The same item can be used in a phantom supply in certain work definitions and a regular stock component in other work definitions.

Phantom Explosion in Process Manufacturing

The phantom explosion in process manufacturing adheres to the following business rules:

• During explosion of a phantom input item, the application restricts to Process Manufacturing work method with no mingling of Discrete Manufacturing and Process Manufacturing work methods.

• Components and resources are inherited to the same operation as phantom input item honors plant parameter for phantom operation inheritance, but ignores multiple output items from the phantom work definition.

• Considers phantom item structures if no phantom work definition exists

• In case of phantom within a phantom, if structure is considered, the work definitions will not be considered again and the explosion continues based only on the structure.
