Many to many relationship with automatic data loading

[Anonymous]

Hello everyone.

I have not a precise question, I just wanted to have some clarifications about how Qlik Sense works.

I have used several Business Intelligence apps but a "many to many" relationship has always been impossible to do because atleast one table mustn't have duplicated values.

This is the case I am working on:

I have not used a custom script and account_id presents duplicated values both in transactions and users.

How does Qlik Sense works in this case?
Does it performs something like a full outer join between Transactions and Users, and an inner join between this table and User Details?

The relations between all the tables are full outer join.

Ah.

Now I understand why I can't find two "id" columns and two "account_id".

Many thanks.

I guess it's always best practice to use a custom loading script therefore...
