System and method for general ledger processing

A computer-implemented system for scalable, customized general ledger processing for a financial institution, the system comprising:

• a memory;
• and
• a processor that is programmed to:
• receive a request from a cheat for one or more reports relating to one or more customized charts of accounts (COAs) for a specified time frame, wherein the one or more customized COAs include client-specific data and third party reference data;
• automatically receive, via one or more sub-processes running on each node in a Hadoop cluster, source information from a plurality of accounting software systems for one or more global find services divisions of the financial institution, specialized systems for tracking derivatives, hank loans, private equity and alternative investments, and third-party sources for tracking sources held outside the financial institution, post tax or regulatory adjusting entries, and other memo entries, the source information comprising accounting data including position data and transaction data, as well as reference metadata comprising information defining one or more general ledger events, chart of accounts, posting rules, and mapping data;
• structure the source information by partitioning the accounting data at an account and a date level for distributed, parallel processing;
• distribute the partitioned source information in a statistically even distribution across a plurality of nodes in a distributed computer architecture used for parallel storage and processing;
• generate debit and credit postings for a balance sheet, the postings comprising per transaction amount postings, per type postings, per GAAP postings, and per lifecycle data, using the reference metadata to define one or more rules for generation of the debit and credit postings, by performing one or more accounting calculations on the statistically evenly distributed source information simultaneously across the plurality of nodes in the distributed computer architecture, the one or more rules comprising a simple mapping of the debit and credit postings from a source account to one or more target accounts when the source information includes one or more debit and credit journals, and a construction of the debit and credit postings from a plurality of transaction parameters identified from the transaction data;
• simultaneously create, with the debit and credit postings, a plurality of discrete views for one of the one or more customized COAs, the plurality of discrete views comprising one or more client view and a plurality of separately calculated GAAP views accounting for disparate GAAP periodicity, timing, FIFO/average cost method, and amortization, wherein the separately calculated GAAP views are created by processing a plurality of transactions comprising the transaction data under a plurality of varied GAAP methods, and further including event subtype qualifiers defining a purpose behind one or more fields and security IDs;
• and
• provide the client requested one or more reports electronically to the client in accordance with the specified time frame.
