system.kanoa.cmms.getMaintenanceBacklogAging(startDate, assetPath, maintenanceTypeName)
Returns the open maintenance work order backlog, bucketed by how long each item has been sitting open (backlog aging), as of a given start date.
Results can optionally be narrowed to a single asset (via assetPath) and/or a single maintenance type, or left unfiltered to aggregate across all assets/types.
This is typically used to populate a backlog-aging chart or table on a maintenance dashboard, helping supervisors spot work orders that have gone unaddressed the longest.
Parameters
startDate DateTime
assetPath String: Can be None for all
maintenanceTypeName String: Can be None for all
Returns
backlogAging pyDataset
Example
# Show open backlog aging for the last 90 days, across all assets and maintenance types
