"windows", I think you mean sheets ?
Blue means it's the primary data source
Orange means it's the secondary data source
Once you link the 2 data sources (find a common field to use as a link), you can use the data from both sources.
the problem is that when I change the Data source all the sheets are changed, and i just want to change some sheets. I also replicated the sheets ,with the objective that my all sheets don´t changed.
