About Item-Product Scope

A Item-Product scope is defined by an implement link from a reference item to a reference product.

The scope link specifies a contract between the item and the product. It delimits a subset of the product structure that can be implemented by an item. Additional scope links can be defined at lower levels of the structures to further identify which parts can be implemented by specific items.

In the figure below, the reference Manufacturing Assembly A:

• Creates and manufactures the reference Product A.
• Implements all the parts of Product A.
• Cannot implement a product that is not part of the Product A structure.

It is possible to define subcontracts. For example, item Sub Assembly 2 has a contract with Product B: it creates and manufactures Product B and implements all the parts of that product.

When a Item-Product scope is defined, a mask appears on the item.

An orange circle appears on the item node in the tree.

A collaborative working environment can be set up using Item-Product scope links.

An item-by-item collaborative working environment can be set up as follows:

• User A is responsible for Manufacturing Assembly A.
• User B is responsible for Sub Assembly 2.

User A is not concerned about the planning of Product B. The work that remains to be done is clear because the scope of the work is defined and identifiable.

User A does not need to know how Product B is manufactured.

User B is not concerned about the planning of Product A. The work that remains to be done is clear because the scope of the work is defined and identifiable.

Multiple reference items can implement the same reference product using Item-Product scope links.

In this way, the items can describe different revisions or alternates of Product A.

The Item-Product scope enables a subassembly to be reused or carried over into another Manufacturing Assembly structure.

In the figures below, Sub Assembly 2 is used in both Manufacturing Assembly A and D.

An assignment filter delimits an area inside a scope on which parts can be selected. It also allows for defining intermediate manufactured assemblies. The available assignable products in the Assignment Manager and Assignment Assistant are limited to the content of the selected engineering assemblies.

You can only assign parts that are similar and inside a scope link. You cannot select parts outside of the assignment filter.

For example, in the following chart depicting assignment filters, any part of eA1.1 and eA2.1 can be assigned to mA1.1, but no part of eA3.1 can be assigned to mA1.1.

When you define an assignment filter on an item, it applies to all its children. If a child also has assignment filters, the assignable products are the intersection of the parent and the child assignment filters.

Tip: You can modify this behavior to limit assignment filters to the first child level only. Select the Apply Assignment Filter at One Level option in Me > Preferences > App Preferences > Simulation > Process Engineering > Service Process Structure > Manufactured Items Management.

You can manage assignment filters with the Manage Assignment Filters command in the Authoring section of the action bar. With this command, you can create, remove, and reconnect assignment filters. For more information, see Managing Assignment Filters.

Impact on assignment commands:

• You cannot assign a product using drag-and-drop if it has an assignment filter.
• Only products belonging to an assignment filter are available for assignment in the Assignment Manager, the Assignment Assistant, and Smart Zoom for B.I. Essentials.
• The Relations panel shows assignment filter information.

An inconsistent Item-Product scope can be a broken or a resolved scope.

Types of inconsistent Item-Product scopes:

• Broken scope: when the scoped product is not loaded in the session or is removed from the tree.
• Resolved scope: when a scope is reconnected but it has a related implement link that refers to a reference product and not a scoped product.

You can manage inconsistent Item-Product scopes using the Manage Inconsistent Item-Product Scopes command in the Authoring section of the action bar. For more information, see Reconnect or Resolve an Inconsistent Item-Product Scope.
