I have two data sources joined. I have a date column in a data source and I have two dates in the other data source. I joined the sources with a non-date column. I would like to count "sales" according to sales date, and count "forms" according to form dates and lastly, I would like to sum costs and clicks according to advertisement dates. I would like to show them on single sheet with a common date column. I have read all related titles on the Tableau forums, but there is no solution that I saw. Can you help me please?
