When you follow the Business Continuity Management documentation then this page mentions BIA Configuration and BIA templates:
however if you only have Business Continuity Planning installed then these modules will not be available.
The Business Continuity Management application consists of multiple plugins. To have access to BIA configuration and BIA templates you need to make sure to have the GRC: Business Impact Analysis plugin installed.
Install the GRC: Business Impact Analysis plugin (sn_bia) from the ServiceNow Store.
