连续缺勤/工作日 Power BI 度量

Question

我目前正在尝试动态计算一组员工的连续工作天数和缺勤天数，但事实证明这是一项相当艰巨的任务。 RAW 表如下所示：

Date	ID	Absent
6/1/2021	1234	1
6/2/2021	1234	1
6/32021	1234	1
6/4/2021	1234	0
6/1/2021	6789	1
6/2/2021	6789	0

我想使用 Dax（不是 Power Query）来计算他们缺席的连续天数，我最接近的解决方案如下，大喊 SQLBI：

DaysWith0 = 
VAR CurrentDate = MAX('Calendar'[Date])
VAR FirstDateEver =  CALCULATE(MIN( 'Calendar'[Date]), REMOVEFILTERS())
VAR PrevWorked =
    CALCULATE(
        MAX('RawDataTable'[Date]),'Calendar'[Date] <= CurrentDate) 
VAR PrevDate = COALESCE(PrevWorked,FirstDateEver)
VAR Result = INT(CurrentDate - PrevDate)  
RETURN
    Result

但这仅计算没有数据（无计划）的连续天数。我需要 2 个度量来显示连续工作日和连续缺勤。

Answer 1

这看起来像一个经典的峡岛

示例

Select DateR1 = min(Date)
      ,DateR2 = max(Date)
      ,ID
      ,Absent = sum( case when Absent=1 then 1 else 0 end )
      ,Worked = sum( case when Absent=0 then 1 else 0 end )
 From  (
        Select *
              ,Grp = datediff(day,'1900-01-01',Date) - row_number() over (partition by ID,Absent order by Date) 
         From YourTable
       ) A
 Group By ID,Grp
 Order By ID,min(Date)

结果

DateR1      DateR2      ID      Absent  Worked
2021-06-01  2021-06-03  1234    3       0
2021-06-04  2021-06-04  1234    0       1
2021-06-01  2021-06-01  6789    1       0
2021-06-02  2021-06-02  6789    0       1
