In January this year SAP released the second version of the Travel Accelerator. This article has a purpose of familiarizing the reader with the concept of the Travel Accelerator 2.0, its capabilities and limitations.
I think there are few companies with hundreds of specialists in the world who are able to build the custom solutions using Travel Accelerator.
Understanding this topic should make this circle of knowledgeable hybris people larger.
There is some documentation that comes with the installation package, however, the documentation from the version 2 explains only the updates of 2.0.
The major part of the documentation that was written for the first version has not been included in the second version for some reason.
I hope this comprehensive article will help you to see a big picture and understand how Travel Accelerator works.
