AAE - Workflow

Hi experts,

I am new to SAP PI. I read some documents related to SAP PI's AAE in SAP PI7.1 and configured a scenario with IC. The scenario is working fine.

By doubt is,

1. When i give interface name wrong, the scenario works well. Why?

2. When i dont give mandatory field, error doesn't occurs. Why?

3. How does AAE works?

Thanks in advance.
