Can't Create Knowledge Ownership Group - Zurich Platform

[GeorgeO]

As in title. Can't create a Knowledge Ownership Group (even with knowledge_admin role assigned).
The glide.knowman.ownership_group.enabled property is enabled, per this documentation:

Activation information

To enable the use of ownership groups, enable the glide.knowman.ownership_group.enabled property. This property is available when the Knowledge Management Advanced plugin (com.snc.knowledge_advanced) is activated. By default, the property is disabled.

When attempting to create an ownership group in our production instance, I see the following error.

Unsure what I'm doing wrong. Any guidance appreciated.

Question cross-posted to Knowledge Management forum, but that forum doesn't seem to have much traction.

It looks like a combination of things, but mostly related to the catalog item you are trying to use to manage the knowledge ownership groups. I'm checking this in my PDI, but there are a few things that could be causing the problem so not sure where to start to be honest. How is the catalog item in your instance actually configured?

Thanks - you were right. SysAdmin had not enabled the catalog item for requesting a group.
