A system, method and carrier medium for configuring processing relationships among entities of a Financial Service Organization (FSO). The system, method and carrier medium may be used for processing and reporting FSO business data including transactional data. A business structure, which may include the processing relationship between various entities of the FSO, may be defined. A processing relationship configuration program may be used to create a processing relationship structure. A node may be created and uniquely defined to represent an FSO physical entity and/or an FSO function. Nodes structures may be defined to correspond to the processing relationship structure within an FSO. A node number may uniquely identify a node instance in the processing relationship structure. An FSO database table may be used to store the a processing relationship structure information. FSO transactions, such as executing a report, may be generated based on the defined processing relationship structure.
