SAP Build Work Zone administrator types are divided into three levels: company, workspace, and area. Each level has a corresponding role collection that needs to be assigned to the users who perform administrative tasks at that level. The company administrator role collection enables users to manage the overall SAP Build Work Zone service instance, such as creating workspaces, assigning workspace administrators, and configuring global settings. The support administrator role collection enables users to access the support portal and perform tasks such as viewing logs, monitoring performance, and managing incidents. The workspace administrator role collection enables users to manage a specific workspace, such as creating areas, assigning area administrators, and configuring workspace settings. The sub-workspace administrator and area administrator types do not require a role collection assignment, as they are created and managed within the SAP Build Work Zone content manager by the workspace administrator or the area administrator respectively.Reference:
