SAP XI Monitoring PI 7.1

Hi all,

I am new to SAP XI and will be working on XI support. My job will be to monitor messages and interfaces across transactions.

Please help me with links/reading material for PI 7.1. Also, what are the different types of XI transactions and possible error scenarios?

Please post any relevant link that will help me understand more about XI process monitoring.

Thanks
