具有&& (多条件)变量数据类型错误的IF

Question

我对康德有疑问。与&(和)。

当我使用单个if条件时，例如：

Column =
IF (
    'For PwerBi'[Cert type for TAT] = "Midterm Routine"
        && INT ( 24 * 'For PwerBi'[TAT excluding weekends_holidays] ) > 8,
    ">8Hrs",
    "NA"
)

我不会得到一个错误和输出来。

但是，当我添加一个IF条件时，比如：

Column =
IF (
    'For PwerBi'[Cert type for TAT] = "Midterm Routine"
        && INT ( 24 * 'For PwerBi'[TAT excluding weekends_holidays] ) < 8,
    INT ( 24 * [TAT excluding weekends_holidays] ),
    "NA"
)

它给了我一个错误：

“生成可变数据类型的表达式不能用于定义计算的列。”

我不明白这个错误的意思。为什么会出现？

这是我最初的dax公式-

Column 2 = IF('For PwerBi'[Cert type for TAT]="MR" && INT(24*'For PwerBi'[TAT excluding weekends_holidays])>8,">8Hrs",

IF('For PwerBi'[Cert type for TAT]="MR" && INT(24*'For PwerBi'[TAT excluding weekends_holidays])<=8,FORMAT( INT ( 24 * [TAT excluding weekends_holidays] ), "0" ),

Answer 1

您的度量不能同时输出数字和文本。你必须选择一个或另一个。在第一个衡量标准中，这两个结果都是文本。在第二部分中，您的True结果是一个数字，而您的False结果是文本。

要解决这个问题，可以使用 function将数字转换为文本。

Column =
IF (
    'For PwerBi'[Cert type for TAT] = "Midterm Routine"
        && INT ( 24 * 'For PwerBi'[TAT excluding weekends_holidays] ) < 8,
    FORMAT( INT ( 24 * [TAT excluding weekends_holidays] ), "0" ),
    "NA"
)
