FDM.4:0 - Use this when
Use this pattern when someone says a financial action is complete but the resulting position is uncertain. Approval, a sent instruction, a system posting and settlement can support different claims.
The pattern governs an account of an actual action or event’s financial effect. It returns a supported change, supported non-change or a specific unresolved effect, including the remaining position where that matters.
Use an adequate established effect account directly. Reconstructing an uncontested payment from every source adds no value when the receiving use already has sufficient evidence.
