Hi,

We are receiving some XML messages from XI 3.0 to mail, XML messages is very long and different type of errors like mapping or adaptors and so on...

My question is how to differentiate thease messages to diffrent user for example if we received mapping errro goes through abap users... if adaptors goes through basis users someting like that...

is anyone tell me procedure for that ?
