Problem

The statistics on the first failure created for an asset can be confusing



Solution

The value for the TBF on the Failure is determined by the time of the Failure minus the first of the values below that is found:

1. The OriginalInServiceDate of the asset.
2. The first StatusChangeDate on an AssetStatusHistory object for the asset.
3. The first InstalledOn date for an AssetInstallationHistory object for the asset.


The Original In Service Date can be found on the Properties view, Manufacturer tab, Purchase sub-tab. If you have created your assets before they were put into service, set this value as the time when the asset was put in service to get correct Failure data.
