Notes:

For fields of string type with no actual value, the default value is "/".
To align with the logic of [Enterprise Organizational Financial Management](Reference/Enterprise Organization/Financial Management.md), when a sub-account added to the financial group queries the details of resource monthly bills independently, all amount fields (except coupon paid and discount coupon amount) are defaulted to 0.
Formulas related to amounts:
Need-pay amount = Cash payment amount + Rebate payment amount + Unpaid credit period amount + Credit refund amount + Arrears amount
Nopaid amount = Coupon deduction amount + Discount coupon deduction amount + Discount amount + Write-off amount
Bill amount = Need-pay amount + Nopaid amount`
