Updating the Asset Hierarchy Snapshot for an MTA2

When you create an analysis that includes the primary asset’s descendants, a “snapshot” is taken of the asset’s physical hierarchy. This analysis hierarchy remains static. That is, any changes made to the site’s physical hierarchy are not automatically made to the analysis hierarchy. However, when you add assets to an analysis, you can have APM refresh the analysis hierarchy with any changes that have occurred to the physical hierarchy.

Also, at any time, you can refresh the analysis hierarchy with new information about the physical hierarchy. For example, if a descendant was added to the primary asset in the physical hierarchy, updating the analysis hierarchy adds the descendant to the analysis. If the position of an asset changes in the physical hierarchy, the change is reflected in the analysis.

Note: If you deleted assets from your analysis, updating the snapshot might add them back into the analysis. For example, if you based the analysis on a primary asset and its descendants and then deleted one of the descendants, the update adds it back into the snapshot.

To Update the Asset Hierarchy Snapshot

1.	From either the site’s or asset’s Strategy Development view, open the analysis.

2.	Make sure that editing is enabled.

3.	Select the Facilitation view and the By Hierarchy tab.

4.	Click Refresh at the bottom of the asset hierarchy tree.

5.	In the confirmation dialog that appears, click Yes. The assets’ hierarchy is updated with the latest information from the physical hierarchy.
