About broken links

Changes to the product or plant structure are not automatically updated in the process tree where the occurrence is referenced. This results in a broken link. With this feature, you can identify broken links and search for the possible occurrence that was originally defined, for example, as a consumed part.

When you expand a process to display linked items, each link line includes a symbol indicating the state of the reference:

Symbol	Description
	Occurrence is linked to a product or plant structure.
	Link is broken.
	Occurrence is linked to a product or plant structure that is not currently loaded, or a product or plant structure is loaded but not currently configuring the process structure.

Note

Teamcenter retrieves the status of a link from a run-time property, Mfg0LinkState.

When performing the search for broken links, Teamcenter searches through process structures that you specify and looks for broken links. It then looks through product or plant structures that you specify for likely candidates to repair these links. The search is based on criteria that you can specify in the MPP_DefaultCandidateSearchCriteria preference. Once found, you can have Teamcenter repair these links automatically, or you can choose to select candidates manually from the candidates list.

Your administrator can save search criteria for you to use. You can further modify these criteria and save your modifications to the saved criteria.

When there are many broken links and each broken link has many candidates, a large amount of memory is required for high-speed processing. If the total number of broken links and candidates is too large, for example, 32,000 lines, the memory usage may be a concern if you are performing the search on an underpowered computer. To speed up the search, divide the search scope into smaller pieces to reduce memory usage; for example, select subnodes instead of the root node.

If you see the white link symbol for a line, it means that the occurrence is linked to a product or plant structure that is not currently configuring the process structure. Select Define Configuring Structures from the view menu to specify the product or plant that should configure the process.
