Hi @Jnt1974. This repository is intended for updates to the documentation for SAP AI Core and SAP AI Launchpad on the SAP Help Portal. Could you please clarify the changes you require in that context?

Hi @karu-0711 , thank you for your message and for taking the time to review the PR. Just to clarify, my contribution is not intended to correct or replace any existing documentation related to SAP AI Core or SAP AI Launchpad. The goal of this PR is to provide a complementary, high-level overview of how AI solutions can be leveraged within an SAP S/4HANA implementation context, as an additional reference for readers.
The content is meant to be informational and value-added, focusing on use cases and integration perspectives, rather than official product documentation changes. I believe it can serve as a helpful supplement alongside the existing SAP Help Portal materials.
I'm absolutely open to adjusting the scope, wording, or even relocating the content if you feel a different approach would better align with the repository's purpose.
Please let me know your recommendation.
Thanks again for your guidance.
