Managed Collections in MPMLink provides the ability to work on a trimmed BOM structure. A managed collection is an organized set of objects that is managed as a cohesive group. You can create and manage a managed collection in BOM Transformer and the Folder Contents table. The BOM structure is trimmed or altered based on the objects collected and the collection options that are configured in a managed collection. For more information, see Managed Collections.

Consider the following scenario:

As a manufacturing engineer, you are assigned to work on the engine subassembly of a car. From the entire BOM structure of the car, it will help to work on a trimmed structure, in this case, the engine subassembly. To do so, you can organize the set of objects that are associated only with the engine in a managed collection. Specify car as the context and create a collection of parts that make up the engine subassembly.

When working on a managed collection in BOM Transformer in upstream or downstream, for a given collection of objects in upstream, the downstream displays the equivalent objects and its child parts, and vice versa.
