3242309 - What are the Collaboration Hub attributes "IT Systems" and "Input/Output documents"?

Where can I define the attributes "Input/Output Documents" and "IT System" which are shown in Collaboration Hub?

Image/data in this KBA is from SAP internal systems, sample data, or demo systems. Any resemblance to real data is purely coincidental.

Both attributes are filled automatically by the system, when you associate an element of type "Document" or "IT System" to an element of type "Task" only
