How do I exclude records in a feature class that are contained within another feature class?

I have a workspace where permit data is joined to GIS data through a series of joins. That data is then written into separate feature classes. The 3 datasets in order are as follows BIN Join, BBL Join, a spatial join using the Point On Area Overlayer transformer. After all of these joins happen I'm dumping any remaining unjoined records into a point feature class called Fallout Points. However all of the records from the spatial join are ending up in the Fallout Points layer. How do I exclude them (or delete them after)?

Please add a Tester on the Point output of the PointOnAreaOverlayer, and test for _overlaps = 0. This will find all the points that did not fall inside a polygon.

Hi @kmc5678​,

Please try setting the PointOnAreaOverlayer parameter Areas First to No. This will accept all area features, regardless of the input feature order. The present setting will force the transformer to only test the area features that reach it before the point feature does.

Thanks for your response @daveatsafe​ . However, changing the Areas First setting to No did not result in the exclusion of the spatially joined records from the Fallout Points Layer.

Please post a new screen shot of the workspace, with the number of features displayed. This will help me see where the features are ending up in the workspace.

Sure no problem. I appreciate the assistance. I was also thinking of maybe producing a list of the Spatially Joined features and then deleting them from the Fallout Points using one of the Unique Identifiers as a final step as a work around. Screenshot 2023-08-02 125216

Thanks so much @daveatsafe (Safer)​, the Tester transformer was exactly what I was looking for and I was able to replace the attribute filter I was using for a similar step in the process.
