Controlled creation of reports from table views

A computing system configured to access one or more electronic data sources in response to inputs received via an interactive user interface in order to split a page of a report and automatically calculate data for insertion into the split page, the computing system comprising:

• one or more electronic data sources storing a mathematical graph comprising nodes and edges, wherein:
• the nodes are configured to store at least information associated with financial assets, accounts, individuals, groups, or other entities, and
• the edges are configured to store relationships between nodes, wherein attributes are associated with the nodes and the edges;
• and
• one or more computer processors in communication with the one or more electronic data sources and configured with program instructions to cause the computing system to at least:
• generate interactive user interface data for rendering an interactive user interface, the interactive user interface including:
• a report including at least a first page and at least a report element on the first page, wherein the report element is configured to include one or more metrics;
• a context selection element including a listing of a plurality of contexts based upon which the one or more metrics are calculable, wherein the contexts are associated with nodes of the mathematical graph;
• and
• a splitting factor selection element;
• receive, via the interactive user interface, selections of at least a first context of the plurality of contexts and a first splitting factor;
• determine a plurality of possible values associated with the first splitting factor;
• determine a node of the mathematical graph associated with the first context;
• calculate, by automatic traversal of the mathematical graph from the first node, and based on the first context and a first possible value of the plurality of possible values associated with the first splitting factor, a first one or more metrics for insertion into the report element;
• automatically update the report element on the first page to include the first one or more metrics;
• calculate, by automatic traversal of the mathematical graph from the first node, and based on the first context and a second possible value of the plurality of possible values associated with the first splitting factor, a second one or more metrics for insertion into the report element;
• automatically update the report to include a second page and at least a copy of the report element on the second page;
• and
• automatically update the report element on the second page to include the second one or more metrics.
