Welcome to the Ariba Exchange community!
There are a variety of programs for Ariba and Procurement available at the SAP Learning Hub. The Hub offers self-paced eLearning versions for most of the Ariba classes. You can identify them by the "e" in the name, for example AR510e is the e-Learning version of AR510. Here's a link to the e-Learning catalog: https://training.sap.com/shop/sap-search?q=*&refine%5Bsolution%5D%5BCloud%5D=Cloud&refine%5Bsub-solution%5D%5BAriba%5D=Ariba
You can also sign-up for Ariba Connect to access documentation. Here's the link for new user registration: https://connect.ariba.com/SRWebService/UserRegistration.aspx
