I'm new to FME and impressed by what can be done with it. However, I got stuck regarding some details. I have a PointOnAreaOverlayer transformer and I wonder why the Point output port let's me use all attributes, whereas the Area output port generates no output for some attributes that I need to use. What is the solution here? Thank you!

Are you referring to the yellow triangles on the Area output? They only indicate that a corresponding attribute does not exist on the connected writer. They may still contain values, try inspecting them.

Thank you very much, David. That was it! I was always searching for a missing setting at the Transformer side and completely overlooked that I copied a Writer with manual "User Attributes" settings. In this case, I could change that back to "automatic".
