Hi, I'm trying to join a customer row with start and end dates to a generic calendar in tMap, so that I could get the following result Customer: CustomerX, 2012/01/01, 2012/01/04 Joined with calendar: ... 2012/01/01 2012/01/02 2012/01/03 2012/01/04 ... Output: CustomerX, 2012/01/01 CustomerX, 2012/01/02 CustomerX, 2012/01/03 CustomerX, 2012/01/04 I tried to enter the logic in tMaps "Expr. key" like this: cust.StartDate <= calendar.Date && cust.EndDate >= calendar.Date But it seems that "Expr. key" doesn't work like that. How can I do a join like this?
tIntervalMatch seems to do the lookup backwards. In order to get the correct amount of rows, I need to bring the calendar in as main and use my real data as lookup, so that I can define the correct min/max values. But this prevents me from bringing any other columns from my data except the lookup-column. I could do normalize/denormalize before and after the intervalmatch, but that seems a really clunky solution. Are there any other ways I could achieve what I'm trying to do?
