Error handling: more messages - best practice

[Bormans, Raf]

Hi,
 
In a self defined background method, I perform multiple functions which all
can produce (information/warning/...) messages.
 
After this method (work-item) I want to inform users (by mail or by
workitem) with an overview of all occured messages.
 
The number of messages are undefined.
 
Is there any best practice to do this.
- maybe a mail (how to display a multiline container element with undefined
number of lines i a mail)
- maybe a text attachement to a mail (how to create a text attachement in
the method and bind it to the workflow container?)
- maybe a workitem on a new method with a call dialog (lot of programming to
do)
- maybe ...
 
Kind Regards, Raf
