Hi @1460069841 ,

If I understand correctly you would like to aggregate the time difference between two occurrences to 0-30, 31-60, 61-90, 90+?

The reason why it only returns 30 days is because in essence you're doing this:

WHEN DAYS_BETWEEN(date1, date1+30) < 31 THEN '0-30'

where DATE1 is youre PU_FIRST thingy :)

This is by default always true. So I guess you need to change either one of the date fields.

Second, I do not understand why you add 30 days to a date, to then check the difference. Would'nt it be easier to not add the days?

Hope this helps!
