Hi ,
I have some tables like Customers , Suppliers , Products , Budget , Sales , SalesHist ...
I'm trying to do some ETL Process before modeling ,
but I don't manage to use some basic Joins .
In example , if I need to add some column and try to join between 2 tables the original table isn't duplicated but only join between them.
The purpose was to join the tables , add the new field and remove the fields key connection .
But don't change the original table.
I need to modify the connection between tables but its seems that there are limited tools .
Some advice ?
Thanks
