Searching by supplier product and services to add the supplier in negotiation module

Based on Oracle document that says that one of the supplier products and services uses is to identify suppliers to invite to sourcing negotiations as bellow screenshot.

There is no option to search for suppliers based on the products and services

The search by 'category name' does not support the hierarchy of supplier product and service categories; it only displays the Functional Area Catalog for Purchasing.

Thanks,
