This invention relates to the field of contract reconciliation management technology, specifically disclosing a contract settlement and automatic reconciliation
system and method that deeply integrates business and financial data. After acquiring business performance
data sequences and financial settlement
data sequences, the
system maps them into a two-dimensional time-series
directed graph. Upon receiving an abnormal settlement trigger instruction, it traces back along the flow of funds and penetrates forward along the business-finance mapping to capture affected node clusters. Then, based on the comparison results between the accounting period identifier and the current closing time, it generates inter-period reversal action instructions and original
order reduction action instructions, constructs alternative reversal path chains, and imports them into a virtual sandbox memory for
verification. When the updated amount value is lower than a preset
lower threshold, it triggers
backtracking and reorganization until a legal reversal path scheme is selected. Finally, it calculates a physical disturbance
score by combining the total number of nodes and the total number of inter-period actions, selects the scheme with the lowest
score, and outputs it to the accounting platform to complete the synchronous update of business-finance reconciliation.
