In the recent Hub update for collapsed sub-processes in Value Chain and BPMN diagrams, both element attributes and sub-process attributes are accessible in the side preview panel.
As this wasn't there in the past, we always assigned the attributes at the collapsed sub-process level. It now required more clicks and creates the need to duplicate information in Collaboration Hub. We are requesting a feature to show both the element and sub-process attribute data if it is assigned, and just sub-process attribute data if it is not assigned.
Thank you for your feedback. This issue has been forwarded to our Product Managers as a feature request; as of now we don't have an estimated date of resolution. To request updates regarding the status of this request, please reference ticket number SCS-38537.
