Finding number of dates on which something occurred

in Calculation Engine (Define Fields)

Featured Replies

Hi--

I have the following situation. I get transactions on various dates, and there can be anywhere from several to no transactions on any given day. If there were no transactions for a given date, there will be no record for any transactions -- i.e., there will be a skip of that date in the file.

I need to get a count of how many dates had at least one transaction, but only count each date once -- i.e., don't include multiple records for a single date.

Anyone have an idea of how to do this as a calculation (not a script)?

All My Best,

Jeffrey

Make a value list using the date field (this will strip out duplicate dates). Then make a calcualtion like such...

ValueCount(ValueListItems(Get(FileName); "MyValueListName"))

example attached. user = admin, no password
