Hi,

My few cents, AAE is the improvement of the AE, then the question will be, what does offer AAE that makes an improvement?, there is simple, it skips the ABAP stuck during message processing and improvements in the adapter with more functions a bugs fixed. For me, the better document that you can read about this issue is this http://scn.sap.com/docs/DOC-3767

Hi,

In addition to what Baskar already mentioned. At high level you could say (quotes from SAP Help):

You use the Adapter Engine to connect the Integration Engine to SAP systems (RFC adapter) and external systems.

With the Advanced Adapter Engine you can connect SAP systems and non-SAP systems together.

In other words, AE only allows you to connect to Integration Engine, while AAE is capable of processing the message completely, end to end.

Advance adapter engine through which you can process your message without the help of abap stack engine. In other words, it has all the possible interface adapters like http, idoc.  So you can use Integration configuration object in the directory to configure the interface object to execute in the AAE itself.  Whereas if you have version such as 7.0 and before, you have  adapter engine which is one of the two stacks (abap  is the second one) to process your message. 

Please search scn for the documents on this topic.

All the versions from 7.1 onwards you have AAE.
