A system and method for representing a very large dataset that enables a plan manager to define, based upon an organization modelling object, a delegation modelling object for a very large dataset. A very large dataset delegation of multiple subplans is created whose subplans can then be individually filtered for specific size restrictions. This enables a plan manager to filter the definition of each subplan prior to the execution of the delegation modelling object, precluding any need for higher-level subplans to contain all the data contained in their subordinate subplans. This allows subplans to contain increased levels of detail not included in their superior subplans, detail that will instead only be summarized in higher-level subplans. A subsequent consolidation process will then extract data not found at higher levels from each delegated subplan, and return that data to its original dataset.
