Exception Handling

Hi Guys,

I want to know how to implement Exception Handling. Also When exception handling is used, what does it do? Does it Halt the process, or does it choose another rout? And where will the exceptions show up in the the SXMB_MONI or somewhere else.

Could someone suggest me a blog or something which shows how to implement Exception Handling step by step.

Regards,

Ashish
