Why is the Group By tile in an ETL giving me an error message?
I am trying to collapse my data set into a single row for each date, publication and product and get the error message "Action outputs to an invalid number (0) of actions"
My data is structured as per below:-
Date Product Publication Channel Revenue
1/1 Display Publication A OMP £1000
Where Date, product, publication and channel are equal I would like it to Sum revenue on a single line.
Can anyone help me. I'm fairly new to Domo so apologies if the solution is a simple one.
Thanks in advance
