A client provides the following three files:File A:File B:File C:File A was uploaded using the...

With File A uploaded using the Ads data stream type, the client wishes to create a view incorporating data from Files B & C.

A false connection would occur if VLOOKUP in Data Stream B is used incorrectly to return “Day” and “Installs”. In this scenario, VLOOKUP might inaccurately link data based on MB Name between File B and File A or File C, which do not have a "Day" field to correctly join on. Moreover, "Installs" data in File B doesn't exist, so VLOOKUP cannot correctly return this information. The correct method would be to use the "Media Buy New Name" to link File B and File C since they both have this field, ensuring accurate connection and avoiding data mismatches or false connections.
