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 Select the upstream part that is linked to an out-of-date part.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![](../Windchill_Help_Center/images/MPM_Icon_EquivalentPartSelect.png)
.
The out-of-date downstream parts are selected.
3. Click
Update to Current Upstream Equivalent Object![](../Windchill_Help_Center/images/ExpMPM_EquivalentPartUpdate.png)
.
The parts are updated
