Question

在我的计算 Table 中，变量 AsOfDate 应该由切片器 dim_Date 反映，它也是计算的 table.

计算得出 table CrossTableEffectiveDate 来自 table fact_Premium 与 dim_Date.

有 Date 关系

我收到错误：Circular Dependency Calculated Column

CrossTableEffectiveDate = 
    VAR AsOfDate = VALUE("2019-01-31") //This value should be based on date value in a slicer
    VAR CrossTables =
        CROSSJOIN(

            SUMMARIZE(fact_Premium, 
                fact_Premium[PolicyNumber],
                fact_Premium[CompanyLocationGuid],
                fact_Premium[Coverage],
                fact_Premium[State],
                fact_Premium[SICCode],
                fact_Premium[ASLOB],
                fact_Premium[ProducerGUID],
                "Start", MIN(fact_Premium[EffectiveDate]),
                "End", MAX(fact_Premium[ExpirationDate]),
                "Premium", SUM(fact_Premium[Premium])
                    ),
            'Calendar')
VAR RiskPeriods =
        ADDCOLUMNS(
            FILTER(CrossTables,
                'Calendar'[EoMonth] >= [Start] && 'Calendar'[Month] <= [End] && 'Calendar'[Month] <= AsOfDate),
            "StartRiskMonth", IF([Start] > 'Calendar'[Month], [Start], 'Calendar'[Month]),
            "EndRiskMonth", IF([End] < 'Calendar'[EoMonth], [End], 'Calendar'[EoMonth])
                 )
    RETURN SELECTCOLUMNS(RiskPeriods,
                "PolicyNumber", fact_Premium[PolicyNumber],
                "CompanyLocationGUID", fact_Premium[CompanyLocationGuid],
                "Coverage",fact_Premium[Coverage],
                "State", fact_Premium[State],
                "SICCode",fact_Premium[SICCode],
                "ASLOB", fact_Premium[ASLOB],
                "ProducerGUID",fact_Premium[ProducerGUID],
                "StartRiskMonth", [StartRiskMonth],
                "EndRiskMonth", [EndRiskMonth],
                "YearNum", YEAR('Calendar'[Month]),
                "Qtr", ROUNDUP(MONTH('Calendar'[Month])/3, 0),
                "MonthNum", MONTH('Calendar'[Month]),
                "WrittenPremium", [Premium],
                "DaysInMonth", [EndRiskMonth] - [StartRiskMonth] + 1,
                //"EndRiskMonth-Start", [EndRiskMonth] - [StartRiskMonth] + 1,
                //"End-Start",[End] - [Start] + 1,
                "EarnedPremium", [Premium] *
                    DIVIDE([EndRiskMonth] - [StartRiskMonth] + 1, [End] - [Start] + 1))

如何使 AsOfDate 变量被 dim_Date 中的 Date 切片器引用？

Answer 1

计算的 table 或计算的列不能依赖于切片器。

这些仅在每次数据加载时计算一次，并且不会响应您在报告中进行的任何过滤。

您可以对这个想法表示支持，以提高 Microsoft 实施它的机会。
