业务背景：企业的采购订单，已入库，确认应付，未付款给对方，财务认为生成财务应付后需要控制申请付款的金额，但是系统的金额控制在付款单。
二开解决方案：在付款申请单保存按钮增加一个金额的校验。校验逻辑：申请付款最大金额=采购预付-（财务应付+付款申请关联金额-已结算金额）
场景A：
采购订单预付100
处理前：
采购订单 → 入库80 → 暂估应付80 → 财务应付80
采购订单 → 付款申请A 100
财务应付80 → 付款申请B 80
处理后：
采购订单 → 入库80 → 暂估应付80 → 财务应付80
采购订单 → 付款申请20(Max)
控制逻辑：申请付款最大金额=采购预付-（财务应付+付款申请关联金额-已结算金额）
此时由于财务应付未继续下推付款申请和付款，已结算金额为0
即申请付款金额<=100-(80+0-0)=20
场景B：
采购订单预付100
处理前：
采购订单 → 入库80 → 暂估应付80 → 财务应付80
采购订单 → 付款申请A 10
采购订单 → 付款申请B 90(Max)
采购订单预付100
处理后：
采购订单 → 入库80 → 暂估应付80 → 财务应付80
采购订单 → 付款申请A 10
采购订单 → 付款申请B 10(Max)
控制逻辑：申请付款最大金额=采购预付-（财务应付+付款申请关联金额-已结算金额）
此时由于财务应付未继续下推付款申请和付款，已结算金额为0
即申请付款金额<=100-(80+10-0)=10
后续流程1:财务应付80 → 付款申请C 80 → 付款80(与财务应付核销80)
此时付款申请关联金额为80，已结算金额为80，申请付款最大金额为10不变
后续流程2:付款申请A 10 → 付款 10(与财务应付核销10)
此时付款申请关联金额为10，已结算金额为10，申请付款最大金额为100-(80+10-10)=20
场景C：
采购订单预付100
处理前：
采购订单 → 付款申请A 10
采购订单 → 入库80 → 暂估应付80 → 财务应付80
采购订单 → 付款申请B 90(Max)
处理后：
采购订单 → 付款申请A 10
采购订单 → 入库80 → 暂估应付80 → 财务应付80
采购订单 → 付款申请B 10(Max)
控制逻辑与场景B相同
