I have been working on Microsoft Portal Architecture for more than 9 years, i am interested towards SAP Ariba. Could you please provide some information on the best books to read about SAP Ariba to start with.
- You can follow the course introduction to Ariba in Open SAP MOOC
- And finally, and this is where there's most of the documents about Ariba, by connecting to Ariba Exchange User Community
Please note that Only content authored by Ariba Documentation is the official Product Documentation of Ariba. You asked if there's a book about Ariba ? Well I don't think so, and even if a book has been published, it wouldn't be a trustful ressource if it's not authored by Ariba Documentation. Therefore, I advise you to start with Open SAP which provide a great insight about Ariba Solution in a very interactive way.
