How to identify polygons that intersect and or overlap each other and collect the feature attribution from the overlaps?

I have 2 polygon shapefiles. I want to identify polygons (A,B,C.... labeled in JPG) that intersect with another set of polygons (Abstract #1, #2, #3,#4). Once the Abstract polygons that intersect are identified, I'd like to merge just the attributions from these into the A,B,C polygons.

I'm attempting to use the SpatialRelator but I'm having difficulties.

Single Shapfile with this attribution:

Polygon A ---(Abstract 1,2,3,4)

Polygon B---(Abstract 1,2,4)

 

Thanks in advance

AreaonAreaOverlayer is the transformer that you want to use.

It will merge the attributes and clip if the polygons overlap partly.

And if you do not want to Clip the polygons, the SpatialFilter transformer can be used.

I'd try a different test, just to prove that it is working. Also, I wonder if there are aggregate features there? Try putting a Deaggregator transformer before the SpatialRelator?
