ALLOCATING HERITAGE INFORMATION IN DATA MODELS

Various embodiments are directed towards including heritage information when allocating costs for a plurality of cost objects. A target object, a source object and heritage objects may be determined from a data model. At least one line item in the source object may be generated by allocating costs from the heritage objects with the generated source object line items corresponding to a line item from a heritage object. At least one line item in the target object may be generated based on allocating costs from the source object. And, at least one generated target object line item may be based on at least one source object line item and its corresponding heritage object line item. A final cost value for the target object may be generated based on a sum of each target object line item and displayed in the data model.
