Stack two data sets keeping only common columns

[davidmakovoz]

I have two datasets. They share some columns and some columns are different. I'd like to stack them (appending rows of the second dataset to the rows of the first dataset) but only keeping the columns they have in common. I can stack them using the Union tool, but I couldn't find an option to 'stack only keeping the common columns'. 

Thanks

Hi Davidmakovoz.

There is the option to output only the common subset of fields from within the union tool.

Hope that helps.
