Inconsistent Links on Tracks

In Simulation and PPR contexts, you can identify track objects that have inconsistent links to other objects, and repair such links (using delete, automatic reconnect, and so on).

Track Objects

Track objects are features created in the Assembly Evaluation app in either Simulation context or PPR context.

Track objects created in Simulation context are:

  • track on a product
  • track for manufactured item (linked to a manufactured item and a capable resource)

Track on an operation (linked to an operation and a used resource) is the only track object that can be created in PPR context.

Track objects are features that belong to a representation. This representation is a child of a reference (scenario, operation or resource). They can be linked to various objects. In most cases, the target object is a instance and more precisely a path of instances (an occurrence in session).

Note that, for a track under operation, only the links on previous operations are managed. The implement link between operation and item is managed in Process Planning and not in Assembly Evaluation. So a track under operation moving the item implemented by this operation never has an inconsistent link.

Causes of Inconsistent Links

Inconsistent links appear mainly when the referenced (target) object is deleted, not loaded, replaced or moved.

In the B.I. Essentials panel, you can use Track Link Status to identify track objects with inconsistent links.

Note: To access the B.I. Essentials list, from the Tools section of the action bar, select B.I. Essentials . For more information, see Track Link Status.

The scenarios that can lead to inconsistent links are briefly described below.

Target Object is Deleted

If a product, item, production system, operation or resource instance is deleted, the link between this object and the track object is broken.

The way to repair the track object is to delete the link.

Target Object is Not Loaded

If a product, item, production system, operation or resource instance is not loaded, the link between this object and the track object is not consistent.

The way to repair the track object is to delete the link.

Target Object is Replaced by a New Version

If a product, item, production system, operation or resource instance is replaced by a new version, the link between this object and the track object is broken.

The last version of the object is proposed if it is found in the session.

Target Object is Moved in the Structure

If a product, item, production system, operation or resource instance is moved in the structure, the link between this object and the track object is broken.

You can repair the track object by deleting the link and rerouting it to another instance with the same reference if at least one exists in the session.

The deletion can be managed in the Link Management dialog box by right-clicking the invalid product and selecting Delete inconsistent link.

Reconnecting the link can be managed by editing the track and selecting the new moving object. No available element is proposed in the Link Management dialog box. You must author the track and select the moving object.

Links Management Dialog Box

For a selected track object, the Links Management dialog box lists the linked objects and the status of the links. Contextual commands allow you to repair inconsistent links.

The Links Management dialog box appears after selecting a track and clicking Link Management .



The Associated Elements section contains all the objects referenced by the selected track object.

The Available Elements section contains all the objects that it is possible to link to the selected track object.

In both sections, the objects are displayed in a table with their name on the left side and in a local 3D viewer on the right (if the link is still valid).

Information is the same in the table and in the corresponding local 3D viewer. Cross-highlighting ensures that an object selected in the table is also selected in the local 3D viewer, the main 3D viewer, and the tree.

Tab pages allow the linked objects to be organized by type (Products and Resources). Tab pages are switched simultaneously in the associated and available sections. For example, if you select a tab page in the associated section, this tab page is also activated in available section.

If a single object type is linked to the track object (Product Track, for example), no tab page is displayed.

The tab pages are used to separate the table content, but local 3D viewers contain all the object types.

Link Status

There are three families of link status: a global status for the track object, a status by tab page (group of linked objects of same nature) and a precise status for each link of the track object.

Global status on track object appears at the top of the Associated Elements section.

  • means at least one link is broken
  • means all the links are OK
  • means no object is associated to the track object

The Status by tab page appears each tab page of the Associated Elements section.

  • means at least one link is broken
  • means all the links are OK

Status for each linked object appear on the table of the Associated elements section, in front of the name of the linked object.

  • No icon means link is OK
  • means target of the link is not loaded
  • means target of the link is not valid

The target of a link is not valid in all the cases described in Causes of Inconsistent Links except the "not loaded" case.

Available Elements

The available elements mainly come from the reroute proposal. For a track under operation they also come from the regular available elements.

To clearly identify the reroute proposals, they are displayed with a specific icon .
