Technical Details This topic provides information about how APM transfers data from the wrong asset to the correct asset during a hierarchy correction. Asset Installation History For a component swap that was not recorded, the existing asset installation history records for the asset(s) being uninstalled are closed off. New installation history records are created for the asset(s) being installed. For an incorrect component swap, the asset installation history records that were created for the wrong component are changed to reference the correct component. The indicator accumulator instance referenced by the asset installation history record is changed to reflect an accumulator for the correct asset. Asset Lives If a new asset life was created for any of the asset status changes that need to be undone, the new asset life is also undone. The existing “undo last component life” method on the asset is used to undo the asset life. Indicator Readings Any indicator readings recorded against the component to be uninstalled or any of its descendents during the error time frame are corrected. Indicator readings that are calculated based on other readings will not be corrected. The table below lists the type of indicator, the readings that are affected, and how they are corrected. Indicator Type Processing Processing Details Numeric and Descriptive Readings affected Readings posted to the component to be uninstalled or any of its descendents. Separate readings are created for the component and location. The location readings are correct; only the component needs to be fixed. Corrective action The reading’s asset is changed to the equivalent asset to be installed (based on matched assets listed in the Hierarchy Corrections Transaction dialog, Assets tab). Any active alarms on the component to be uninstalled and its descendents that result from the transferred readings are removed. The alarms on the component to be installed and its descendents are reassessed using the transferred readings. Cumulative Readings affected Readings posted to the component to be uninstalled or any of its descendents. Separate readings are NOT created for the component and location. The single reading is posted to both the component and location. By using the reading’s list of “assets posted to,” readings for both the component and location will be picked up. Corrective action Reverse the original reading. This method uses the reading’s list of “assets posted to” to determine the assets to be updated. Create a new reading. The new reading is a copy of the original that is posted using the corrected hierarchy. Work Requests For a component swap that was not recorded, any work requests created during the error time frame for the component that was uninstalled or any of its descendents will be updated with the correct component. For an incorrect component swap, the work requests do not need to be corrected because they reference the location and whatever component is installed in that location. Once the correct component is recorded as installed in APM, existing work requests will automatically reference the new component. Work Order Tasks For a component swap that was not recorded, work order tasks that list the component to be uninstalled or any of its descendents as the asset to work on or the asset to charge will be updated. Any work order tasks created or closed during the error time frame are corrected as follows: • The asset to work on will be set to the equivalent asset to be installed (equivalent asset is based on the matched assets listed on the Hierarchy Correction Transaction dialog, Assets tab). • The asset to charge will be set to the equivalent asset to be installed. • APM will recalculate the contents of the assets in history relationship for canceled or closed work order tasks. • Installed component and component installed relationships are reset. • Indicator snapshots are recalculated. If the task is closed, the values will be set to the at-creation value. • Planned component swaps are updated with the assets to be installed. • Planned resource demands for external repairs are updated with the assets to be installed. • Any asset indicators on the task’s list of indicators to be read are updated to the equivalent asset to be installed. For an incorrect component swap, work order tasks that list the component location or its descendent locations as the asset to charge have to be updated. Any work order tasks created or closed during the error time frame are corrected as follows: • APM will recalculate the contents of the assets in history relationship for canceled or closed work order tasks. • Installed component and component installed relationships are reset.
