Question

状态：

IIf([Ongoing]=True,"Ongoing",
   IIf([DueOut]![Completed]=True,"Completed", 
     IIf([DueOut]![Suspense]<Date(),"Overdue",
        IIf(DateDiff("d",Date(),[Suspense])<6,"This Week",
           IIf(DateDiff("d",Date(),[Suspense]) Between 7 And 14,"Next Week","Greater than 2 Weeks", 
               IIf([Suspense]>30,date(),"greater than 30 days")
           )
         )
       )
    )

我一直在尝试添加“超过30天”的方面遇到错误。

Answer 1

请在不能使用CASE函数时嵌套那么多IIF语句。

CASE([Ongoing]=True,"Ongoing",
[DueOut]![Completed]=True,"Completed", 
[DueOut]![Suspense]<Date(),"Overdue",
DateDiff("d",Date(),[Suspense])< 7,"This Week",
DateDiff("d",Date(),[Suspense]) < 14,"Next Week",
DateDiff("d",Date(),[Suspense]) < 30, "Greater than 2 Weeks"
True, "Greater than 30 days")

（还修正了一些语法）

只是语法错误...你的倒数第二个IIf语句与你编写它的方式有四个参数。看来当你将最后一个IIf卡在那里时，你只是没有将它正确地整合到前一个IIf([Ongoing],"Ongoing", IIf([DueOut]![Completed]=True,"Completed", IIf([DueOut]![Suspense]<Date(),"Overdue", IIf(DateDiff("d",Date(),[DueOut]![Suspense]) <6,"This Week", IIf(DateDiff("d",Date(),[DueOut]![Suspense]) <14,"Next Week", IIf(DateDiff("d",Date(),[DueOut]![Suspense]) <30, "Greater than 2 Weeks", "Greater than 30 days" ) ) ) ) ) )中。试试这个：

Ongoing

现在它在语法上有效，但我会质疑你的逻辑。对于尚未到期的项目（本周，下周等），他们也Ongoing？如果是这样，逻辑将永远不会到达“本周/下周”代码部分。它只会返回“正在进行”。如果我误解了如何使用IIf([DueOut]![Completed],"Completed", IIf([DueOut]![Suspense]<Date(),"Overdue", IIf(DateDiff("d",Date(),[DueOut]![Suspense]) <6,"This Week", IIf(DateDiff("d",Date(),[DueOut]![Suspense]) <14,"Next Week", IIf(DateDiff("d",Date(),[DueOut]![Suspense]) <30, "Greater than 2 Weeks", "Greater than 30 days" ) ) ) ) )标志，那么你可能没问题，但是如果 - 通过“持续” - 你想要显示它们何时到期，那么你永远不会希望它返回“正在进行的”。您可能需要“已完成”，“过期”或到期时的描述。 如果是这种情况（并且我不确定它是否是），那么试试这个：
