spotfire-如何找到创建一个列来计算下一阶段的时间

Question

我想创建一个计算列来显示按 [案例 ID]、[阶段] 和 [操作] 分组的操作结束时间。舞台的顺序不必按字母顺序排列，可以重复。说在[stage]'C'之后，我们以后可以再[stage]'c'

谢谢，

Answer 1

感谢更新测试数据。询问时，数据类型极其重要。此外，测试数据应尽可能接近实际数据，否则解决方案通常无法扩展。例如，在测试数据中，值只是时间。按时排序不考虑日期，因此都一视同仁。由于这些值实际上是 DateTime，因此我已将其添加到测试数据中。这些表达式将为您提供问题中确定的预期结果。

Rank([Time_Action_Begin],"asc",[Case ID]) as [Rank]
Min([Time_Action_Begin]) OVER (Intersect([Case ID],Next([Rank])))

结果

+---------+-------+----------+------------------------+------------------------+------+
| Case ID | Stage |  Action  |   Time_Action_Begin    |    Time_Action_End     | Rank |
+---------+-------+----------+------------------------+------------------------+------+
