• Resources of type Skill, Tool, and Processing Material are known as Processing Resources.

• A Work Center has the resource type as Work Center.

• You can allocate a processing resource multiple times to an operation. For example, screwdriver as a processing resource when assembling two variants (V1 and V2) of a car. The number of screwdrivers required during assembly of V1 and V2 are 6 and 8 respectively. In PPB, assign the quantity 6 to screwdriver allotted to V1 and quantity 8 to screwdriver allotted to V2. For more information see, Working with Work Center and Processing Resources in Process Plan Browser.

• You can allocate a part or an assembly as a processing resource of an operation in PPB. For example, in-house designed jigs and fixtures that OEMs use for assembling a product. These jigs and fixtures are also considered as processing resources for the final assembly. For more information see, Allocating a Processing Resource to an Operation in Process Plan Browser.

• A compatibility link cannot exist between processing resources and a work center.

• No compatibility links are allowed on plant and resource groups.

• For any item, it is not possible to set an additional compatibility link to the same item. For example, if for an element A1, a compatibility relationship with element B1 has already been set, it is not possible to create:

◦ one more compatibility link from A1 to B1.

◦ a compatibility link from B1 to A1.
