Visual Composer: Problem with union

[Former Member]

Hi Gurus,

I have a problem with Union. It should be very simple and for this reason there is few threads and one or two blogs about such topic. The only way to define key fields is when I have one query or function linked but as soon as I link other dataset it blanks the key fields area. Any idea?

Regards,

Gilson

Hi Gilson,

Both the data source(BI Query) should have atleast one common field.

Does they have some common field?
