The different catalog names (e.g., 'SaaS Catalog' and 'Lifecycle Catalog') will be unified into 'reference catalog' throughout the different workspace areas (e.g., fact sheet details page of applications and IT components). However, access to the catalog will remain in the same place and contain the content you are familiar with.
The different catalogs in SAP LeanIX converge into one reference catalog with recommendations for various fact sheet types. This means a dedicated 'Reference Catalog' section is now on the inventory's side panel, with links to reference data per fact sheet type.
