This repo wants to give users of the SAP Business Technology Platform (BTP) a quick way to learn how to use generative AI with BTP services.

• You have access to an SAP BTP global account or an existing SAP BTP sub account.

• Visual Studio Code is installed on your machine with the Dev Container extension. You understand purpose and basic concepts of Dev Containers in VS Code.

• As prerequisite for using dev containers, Docker is installed on your machine and you understand its basics concepts.

• Git is available on your machine (test with git --version) and you know how to clone a project from github.

• The SAP BTP global account needs to be sufficiently entitled to use the following services and applications:

  Name	Service/ Application	Plan
  AI Core	aicore (service)	extended
  AI Launchpad (optional)	ai-launchpad (app subscription)	standard
  HANA Cloud	hana-cloud (service)	hana
  HANA Cloud Tools	hana-cloud-tools (app subscription)	tools

• Clone this GitHub repository to your local machine and open it in VS Code.
• Open the Dev Container on your machine from within VS Code (Reopen in Dev Container).
• Wait for the dev container to be built and the project to be loaded within it.

  Be aware that opening the dev container can take a while!

• In the folder config/secrets rename the file btp_ai_setup.tfvars to my_btp_ai_setup.tfvars.
  • adapt the value for globalaccount for the subaccount to be created within. You find in the global account landing page ("Subdomain: .....").
  • if you would like to use custom IDP, provide the value for idp e.g. <your-ias-tenant>.accounts.ondemand.com.
  • add your email address to the variable admins. This should be looking similar to this: admins = ["[email protected]"].
  • save the file.
• In the folder config/secrets rename the file btp_credentials.tfvars to my_btp_credentials.tfvars.
  • adapt the value for the variable BTP_USERNAME to your email address.
  • save the file.
• Within VS Code open a terminal session.
• In the terminal simply type ./run.sh and enter your BTP_PASSWORD as well as the password for the HANA DB (you will be prompted accordingly).

  Make sure that the password for the HANA DB matches the minimum requirements (length >= 8, 1+ upper case chars, 2+ lower case chars, 1+ digit)!

In case you want to authenticate via Single-Sign-On (SSO) you should set the enironment variable BTP_ENABLE_SSO to true. You do this by running the following command within your dev container: export BTP_ENABLE_SSO=true

The startet script will now setup the following things for you in your SAP BTP global account:

• It creates a subaccount with the name configured in the my_btp_ai_setup.tfvars file (folder config/secrets).
• It creates service instances/subscriptions for the following services
  • SAP AI Core (service)
  • SAP HANA Cloud (service) with integrated vector engine
  • SAP HANA Cloud tools (app subscription)
• It creates a file called .env that will be copied into the config/secrets folder.

The second step will automatically be taken care of by the running ./run.sh command from step 1.
After the successful setup of the BTP subaccount, it calls the python script step02_fetch_metadata.py in the folder scripts.

That python script does the following:

• It loads the content of the newly created .env file from step 1 into the environment variables of the session.
• It calls the AI Core APIs to give you access to the models you have defined in the file config/secrets/my_btp_ai_setup.tfvars (through the variable target_ai_core_model).

After the steps above, you are all set for your first genAI experiments on SAP BTP.

You can proceed by switching to the folder scripts/step03_explore_examples.

Here you will find some examples with respective instructions and sample code.

❗There is an existing issue that makes AI Core API token invalid for about 1-2 hours after it was created. We implemented a retry mechanism, nevertheless, until the issue is resolved, running the ./run.sh might result in the following error. As a temporary workaround, just re-run the ./run.sh in 1-2 hours.
