I contacted IBM and found this response interesting:
"I talked with one of my subject matter experts and he said
If there is only one virtual processor, the field will not show up in WRKSYSACT.
If you bump Virtuals up to 2 you should then see the field."

Subject: Virtual Processors not displaying in WRKSYSACT
I noticed on some of my systems that Virtual Processors is not showing in the WRKSYSACT display. When I look at the HMC there are virtual processors configured for these systems. What triggers Virtual Processors to display?
