Question

在我的计算表中，变量AsOfDate应该由切片器dim_Date反映出来，该切片器也是计算表。

从表CrossTableEffectiveDate派生而来的计算表fact_Premium与Date具有dim_Date关系。

我收到错误消息：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中的Date切片器引用dim_Date变量？

Answer 1

您不能让计算表或计算列依赖于切片器。

这些仅在每次数据加载时计算一次，并且不响应您报表中的任何过滤条件。

您可以对此概念添加支持，以提高Microsoft实施该概念的机会。

Dynamic calculated column

循环依赖计算列Power BI桌面
