FIN.4:10 - Architectural Rationale
An operating forecast, an accounting representation and a funding account describe connected consequences through different quantities. Keeping the events behind those quantities visible makes the transformation explainable: a sale creates revenue and perhaps a receivable; collection settles the receivable and supplies cash. The roll-forward retains both meanings instead of choosing whichever number favors the proposed action.
MA supplies the demand and resource construction and the reconciliation of reporting views. FIN.4 adds the receiving financial purpose, the connected position and cash account, and the feedback from financing choices. FIN.6 still owns the project’s incremental comparison, because a coherent company forecast does not identify which consequences belong to one investment rather than its feasible alternative. FIN.7 still owns the continuing-value assumptions. These boundaries allow reuse without leaving those constructions to implication.
More detail is useful when it can reveal a timing gap, nonlinear cost, changed claim or material source discrepancy. It is burdensome when it merely reproduces an already adequate ledger. Choose resolution from the receiving consequence and preserve the route back to the operating assumption when the forecast needs adaptation.
