Power BI使用两个不同表中的日期测量逾期订单

Question

请求：计算逾期的已购买订单数。应用过滤器时重新计算。

背景：有3个表：

• Purchase_Orders包含订单[承诺日期]，
• Received_Orders包含[收到日期]，
• 包含唯一采购订单编号的PO_DIM。

关系：** Purchase_Orders -1 PO_DIM 1 - Received_Orders

衡量Sudo代码：

 1. CountRows
 2. Filter for rows where Purchase_Orders[Promised Date] is not Blank()
 3. Filter for rows where Received_Orders[Received Date] is Blank()
 4. Filter for rows where Purchase_Orders[Promised Date] < Today()

你会如何解决？

Answer 1

我会将3个过滤器需求转换为一个FILTER函数，使用RELATED来测试其他表中的列，如：

Count PO Pastdue =
CALCULATE (
    COUNTROWS ( 'PO_DIM' ),
    FILTER (
        'PO_DIM',
        NOT ( ISBLANK ( RELATED ( Purchase_Orders[Promised Date] ) ) )
            && ISBLANK ( RELATED ( Received_Orders[Received Date] ) )
            && RELATED ( Purchase_Orders[Promised Date] ) < TODAY ()
    )
)
