I want to calculate the average churn, based upon two tables in my model, containing:
Table1
Clientnr Month Subscription
A 201501 1
A 201502 1
B 201501 1
B 201502 1
Table2
Clientnr Month Churn
A 201501 1
A 201502 0
B 201501 1
B 201502 0
Resulting in a form of output where I can see that:
Month Churn%
201501 100%
201502 0%
How do I do this in the report view?
