Our solution provides a planning model administration module to support rapid modification to the model, planning dimensions, formulas, notifications, and planning periods. Changes can be immediately propagated out to forms and reports without involving IT or writing custom code/script. GesFin^TM supports flexible planning periods and models including attribute-based, activity-based, zero-based, prior run-rate based, top-down, bottoms-up, and custom. GesFin^TM is centered on the planning models and their hierarchy with related items such as drivers, attributes, formulas, rules, forms, and reports. This enables unlimited views and manipulation of the model at any level in the hierarchy with real-time calculations.
