I’m in the process of writing a book on SAP Enable Now, tentatively titled SAP Enable Now Development. This book will focus on the development of content by Authors in Producer, and the delivery of this content via the Trainer, Desktop Assistant, and Web Assistant. I’m currently 350+ (of an expected ~500) pages in, with an estimated availability date of year-end 2018. Thanks for your patience.
Update 04-NOV-2018: Now 580 pages and I’m making final edits and sending chapters out for review.
