如何在 DAX for Power BI 报表中写入动态 header

Question

我有两个切片器，报告 header 应该根据切片器中的选定值显示数据。我能够为选定的单个值编写表达式，但是有什么方法可以为多个值编写表达式吗？

Header = 
    var selectyear =  SELECTEDVALUE(dim_Date[Year]) 
    var refreshdate = VALUES(fact_Premium[RefreshDate])
    var datetype = VALUES('Date Type Slicer'[Date Type])
    return "Report Period: " & selectyear & " As Of: " & refreshdate & " PST by " & datetype

对于多个值，如果选择超过 1 年，假设是 2016 年，则应为：

"Report Period 2016 - 2018 As Of 6/4/2018 10:09:36 PST by Accounting Date"

如何修改表达式？

谢谢

Answer 1

如果您选择了多个连续年份，您可以定义一个最大年份和一个最小年份。

Header = 
    var minyear = MIN(dim_Date[Year])
    var maxyear = MAX(dim_Date[Year])
    var refreshdate = VALUES(fact_Premium[RefreshDate])
    var datetype = VALUES('Date Type Slicer'[Date Type])
    return "Report Period: " & minyear & " - " & maxyear & " As Of: " & refreshdate & " PST by " & datetype
