Requirements, principles or guidelines of an accounting standard such as Generally Accepted Accounting Principles (GAAP) are transformed or codified into rules that specify how form, content and/or style of a certain portion of a financial statement, such as a header, should be configured while complying with the accounting standard. A rule engine compares attributes related to a financial statement and rules to determine which rule applies, and a selected rule specifies a header configuration. Relevant data received or retrieved from a source is used to generate or populate the header such that the header is automatically generated while complying with the accounting standard.
