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Parts that are not linked to the most recent iterations of their downstream equivalent parts have an out-of-date icon displayed next to them.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 that is not the most recent iteration:
1. Select the upstream part that is linked to an out-of-date part.
* 
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. Click Select Equivalent Parts on Other Side.
The out-of-date downstream parts are selected.
3. Click Update to Current Upstream Equivalent Object.
The parts are updated and are now available in the downstream Equivalent tab.
