Hey Marc Maleika,
I think that you might need to change the field in the data base.
Another option may be to create a lookup table where it has the date and datetime for each hour, etc and then join to that.
You also could be able to use "data blending" to accomplish this. Are you familiar with that feature?
You'll need to do something like convert the date/time value into a string using the STR function:
....and then truncate some of the characters off the end using the MID() function.
You'll do this in both data sets, then "blend" on the result.
Hope that helps!
The idea is to build a funnel with the data. Tried to follow the Tableau funnel example but my data does not allow to follow these steps. I am missing "phases" in both DBs. Any ideas for a workaround?
