Where would you look to find a suitable partner add-on with industry-specific functionality for SAP S/4HANA Cloud Private Edition?

The most appropriate resource for finding a partner add-on with industry-specific functionality for SAP S/4HANA Cloud Private Edition is the SAP Certified Solutions Directory. This directory is specifically designed to list and showcase solutions that have been certified by SAP, ensuring that they meet the quality and functionality standards associated with SAP products. It provides users with the ability to search for partner solutions that are tailored to various industries, making it easier to find add-ons that fit specific business needs.

The other resources, while valuable, serve different purposes. The Partner-Packaged Solution Finder primarily helps identify packaged solutions that may not necessarily have gone through the same rigor of certification. The SAP Discovery Center focuses on innovative SAP solutions, guides, and best practices, rather than specific partner add-ons. The SAP Partner Portal provides general information and resources for SAP partners but does not specialize in finding certified industry-specific add-ons directly for customers. Thus, the SAP Certified Solutions Directory stands out as the best choice for this particular inquiry.
