Error handling in ccBPM

Hi ,

I would like to know , How to do error analysis in ccBPM?

any best practices are available step by step. checked in William Li's blog and other blogs in SCN. I need to know debug each step in ccBPM( at Integration process )

if I want to check manually each step like Receive, send, Transformation , loop, fork , user decision,wait,undefined,switch,block etc, what is the process to debug in each step?

Thanks

Praveen
