I am new to the community and have been looking at the other posts here, but there does not seems to be a direct answer to my question.
Referencing SAP Note: 2633830 - No Option To Create Business Catalogs in S/4HANA Cloud
At present we are not allowed to create new Business Catalogs. The Custom Catalog Extensions app will allow you to add extensible objects only to existing business catalogs.
In certain instances this would not be suitable and it would be great if there is the ability to use your own custom Business Catalog. (Please keep in mind that the idea here is not to build a custom Business Catalog by picking and choosing existing SAP delivered apps.)
Does anyone know if SAP is planning to enable a feature to build your own Business Catalogs for extensible objects in future?
