Updating Equivalence Links
Parts that are not linked to the most recent iterations of their downstream equivalent parts have an out-of-date icon displayed next to them. To update a part that is linked to an iteration of another part which is not the most recent iteration, perform the following steps:
1. 1. Right-click the upstream part that is linked to an out-of-date downstream part and select Equivalent Parts on Other Side. The out-of-date downstream parts are highlighted.
* 
No equivalent parts are displayed in the Equivalent Parts tab. However, equivalent parts are displayed in the Latest non-linked iteration of downstream equivalent parts matching the filter subtab, and in the downstream view.
2. Right click on the part that is to be updated and select Update to Current Upstream Equivalent Object. The Update Equivalence dialog box opens. The Carry over from upstream checkbox is already selected.
3. Click OK. The parts are updated and made available in the downstream Equivalent tab.
A warning is displayed if the part is checked out by another user. In this scenario, the update cannot be performed.
