Delete features that exist in another layer

[JamesRedford]

Hi there,

I have a problem that I am trying to solve.

I have two feature classes. Feature class A contains ~200 features, and feature class B contains ~1,000 features. All of the features from feature class A are also in feature class B, and I would like to remove the ~200 features that exist in feature class A from feature class B. 

Is there a tool that I am missing that can accomplish this without going one by one through the list and manually deleting?

Thank you!

Use Select Layer By Location to select features in feature class B that "Are identical to" features in feature class A, if they are identical.

Use Delete Features tool on feature class B, which now has the selection, to delete the selected features.

Does that work for you?
