Description:  With this app, you can view information about maintenance backlogs (requests and orders) for a series of operational planning buckets. To display information in the app, you first select a range of planning buckets by choosing a reference planning bucket and a number of planning buckets in the past and in the future. The analytical cards and quick view cards provide different kinds of information about the selected planning buckets. Both card types let you navigate from the card view to other relevant applications. Note that the Phase filter that is available in the selection area is only applicable for the Maintenance Backlog card. Note This app has been designed to be used within the functional scope of the Reactive Maintenance (4HH) and Proactive Maintenance (4HI) scope items that differs from how the maintenance process had been run before (based on the scope items BH1, BH2 and BJ2). Some of the features might not work in the same way or they might not work at all. Furthermore, not all the features of this Fiori app are available for maintenance orders of order types for which the phase model has not been activated. 
The Maintenance Backlog Overview app will be used by the Maintenance Planner/Supervisor to monitor the various maintenance backlogs (orders).
If the phase model is enabled in the system, this app will enable the Maintenance Planner/Supervisor to monitor the various maintenance backlogs (notifications/orders) distributed across the 9 phases of the maintenance process.
The Planner can also do a proactive review of procurement processes to buy parts and services using a new analytical card that is provided in the app.
Key features:  The Maintenance Backlog card contains a stacked bar chart that shows the total number of phase-enabled maintenance requests and maintenance orders in each of the selected planning buckets. You can display the chart data by phase, maintenance activity type, order and notification type, or priority. When you select one of these categories in the dropdown menu of the card, the X-axis represents the selected planning buckets and the Y-axis shows the number of maintenance requests and orders arranged according to the selected category. If you select one or more phases in the selection area, the system only displays maintenance requests and orders in the selected phases. Depending on the selected category, the chart offers the following navigation options:  If you choose By Maintenance Activity Type, By Order and Notification Type, or By Priority, you navigate to a pre-filtered list of information in the Manage Maintenance Notifications and Orders app.  If you choose By Phase, the navigation is as follows: Navigation By Phase   Maintenance Phase   Target Application      Initiation (01)   Maintenance Supervisor: Screen Maintenance Requests Maintenance Planner: Display Maintenance Notifications     Screening (02)   Maintenance Supervisor: Screen Maintenance Requests Maintenance Planner: Display Maintenance Notifications     Planning (03)   Manage Maintenance Notifications and Orders     Approval (04)   Manage Maintenance Notifications and Orders     Preparation (05)   Manage Maintenance Backlog     Scheduling (06)   Find Maintenance OrdersNote If you have enhanced the core functions of SAP S/4HANA with an additional license for Resource Scheduling, the target application is the Manage Work Center Utilization app.     Execution (07)   Find Maintenance Orders     Post Execution (08)   Find Maintenance Orders     Completion (09)   Find Maintenance Orders    Note If a chart section represents only a single order or notification, the application opens the object page of the order or notification.  If you click on the card header, you navigate to the Manage Maintenance Backlog app. By default, the backlog for the first planning bucket in the chart is displayed.
