So I have monthly measures, of this kind: (billID, start, end) knowing that the correct business specification sets the difference between start, end of one month. So I assume I receive data as so.

Let’s assume in rare cases, I can receive other intervals.

In my case, I don’t want any treatment, except de-duplication and interval overlapping. Setting interval to day, and treatment to integral, seems to be the only solution for me. Am I correct?

Thanks in advance.
