Trees and Reporting
Use reporting trees to:
Map general ledger amounts into Activity-Based Management resource objects.
Generate reports from the PF Ledger table that summarizes results for a particular dimension or business unit.
Without a tree, you would have to explicitly specify which departments to include every time you create a report. By using trees, the system can consult the trees to determine which departments or account groupings to include in reports. In addition, trees give you the option to view information at any level.
