Thank you for your answer.
I'm aware of the fact that I have to recreate the model using the GA connector.
The question is : what is precisely the data model ( the entities and their relationship) and what do I have to select in order to create the model ?
I suppose that afterwards, I have to create the measures // calculated columns and reconciliate the results I get from the model with the corresponding one from the GA reports.
Anyone that has experience with this process and can answer / disclose the model perhaps ?
Thank you.
