Union is removing field descriptions

8 - Asteroid

Hey there!


I'm merging two similar datasets of survey data. Both are similar, with the exception that dataset #1 has more variables (for example, a question has more answer options in dataset #1).


I've matched the files perfect after doing a bit of renaming, and I've unioned the two datasets. My challenge is this: union only copies over common field descriptions. So, any new questions or answer options in dataset #1 does not get copied over.

As you can see from above, there are gaps in the descriptions - these are new variables that are only present in dataset #1 and not dataset #2.


Any idea how I can ensure ALL field descriptions get copied over even if they are only present in one dataset not both?

I *think* I figured it out: Dynamic rename tool.


I used the "take field descriptions from the right input metadata" option in the rename tool, and boom - looks like my blank field now have a description!
