How to iterate process with changing filter?
Contributor IHi,
Now I am working on an event-log and have a question.
Let me briefly explain my data first.
There are attribute 'Case ID' and each 'Case ID' has several instances. In other words, there are 10 columns with case ID = 1.
So I want to filter the data by its 'Case ID', do some process, and aggregate filtered data again. (like 'for loop' in other language)
I tried 'Loop' operator but it doesn't work as I expected.
If you have any idea, please let me know.
Thanks!
