Power Bi DAX：显示开始日期后6个月的数据 [英] Power Bi DAX: Show data from 6 months past start date

问题描述

我一直很难找出如何显示比开始日期晚6个月的数据。

i have been having trouble trying to figure out how to show my data past a date that is 6 months past the start date.

我需要显示值在开始日期之后的6个月之后。

I need to show the values that are after the 6 months past the start date.

每个人的日期都不一样

该公式作为6个月的计算列：
+ 6m = DATEADD（'雇员列表'[Emp。Dates]。[Date]，+6，MONTH）

i have the formula as a calculated column for the 6 months: +6m = DATEADD('Employee List'[Emp. Dates].[Date], +6, MONTH)

一项措施将不起作用，因为由于出现错误，我无法将其应用于我的表。

A measure will not work because i cannot apply it to my table as it comes up with an error.

我如何使其工作？
我应该为新公式删除+ 6m列吗？

How do i get it to work? Should i scrap the +6m column for a new formula?

推荐答案

基本度量：

Total Sales = SUM(Sales[Total Sales])

只要您不提供示例数据，它就在猜测您想要的是什么。可能是这样：

As long as you do not provide sample data, it is just guessing what you want. It might be it:

YourMeasure =
CALCULATE (
    [Total Sales],
    DATEADD (
        'Employee List'[Emp. Dates].[Date] -- it is better to use here 'Calendar'[Date]
        -6,
        MONTH
    )
)

更新

样本数据：

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjIwMtA1MAQiJR0lQ6VYHZiQEaaQMaaQCaaQKaaQGaaQOaaQBaaQJYaQoQGmEKbrDdFdb4jpR0NkP8YCAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Date = _t, Amount = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Date", type date}, {"Amount", Int64.Type}})
in
    #"Changed Type"

Measure = 
var MinDate = CALCULATE( MIN(T[Date]), REMOVEFILTERS(T[Date]) )
var SixMonthAfter = CALCULATE( DATEADD( T[Date], 6 , MONTH ), T[Date] = MinDate )
return
CALCULATE( SUM( T[Amount] ), FILTER( T, T[Date] > SixMonthAfter ) )
