我有基于资源 ID 为每个用户分配项目的表格。我们正在创建一些需要通过Staffed从Demand价值中扣除价值来获得超额分配价值的报告。

基于 , 的组合，需求值是唯一Number的ResourceId。

我必须推导OverStaffed01 = Demand01 - Staffed01但有一次约束，如果我们有重复 的Number和ResourceId，我们必须根据前一行调整需求值。

例如：

的组合Number:RR-00000002 and ResourceId:1019096有三行，所以我们不能直接计算值。

对于第一行，(OverStaffed01 = Demand01 - Staffed01) 0.40 - 0.30 大于 0，所以这不是人满为患，我们认为是 0。

对于第二行（OverStaffed01 = Demand01 - Staffed01）0.10 - 0.70（因为我们已经从第一行减少了 0.30，所以我们将 Demand01 设为 0.10）并且 OverStaffed01 为 -0.60

的组合Number:RR-00000001 and ResourceId:1019094有两行，所以我们不能直接计算值。

对于第一行，(OverStaffed01 = Demand01 - Staffed01) 0.01 - 0.30 是 -0.29。

对于第二行 (OverStaffed01 = Demand01 - Staffed01) 0.00 - 0.40 （因为我们已经从第一行减少了 0.01，所以我们将 Demand01 设为 0）并且 OverStaffed01 为 -0.40

对于第三行 (OverStaffed01 = Demand01 - Staffed01) 0.00 - 0.30 （因为我们已经从第一行减少了 0.01，所以我们将 Demand01 设为 0）并且 OverStaffed01 为 -0.30

对于其他行，我们有唯一的Number和ResourceId，所以我们可以直接扣除和计算OverStaffed01

到目前为止尝试的查询：

更新

我已经发布了我最近更新的查询，它给出了某种正确的结果，但仍然不是预期的结果。
