in which case we use each of them

[dharamveer_gaur2]

Integration Server and Integration Engine are used synonymous with each other. But there is a sublte difference if you actually look into the XI architecture images provded by SAP.

The Integration Server contains,

1. Adapter Engine

2. Business Process Engine

3. Integration Engine.

So, taking this into picture I guess Integartion server is a collection of these 3 while integration engine is one of the runtime components of XI. All messages are processed in the Integration Engine.
