Somehow. My starting Point was the file bopcfg/wwww/htmpl/web/analyst/detail_in.htmpl.
There I saw, that for displaying the Service Type tab the file ""xx_stype_tab.htmpl"" is used.
There I found that the the template iterates through "args.sla_events ".
using "bop_sinfo -dq cr" told me that "cr.sla_events " holds a list of atev objects.
The rest of the Information can be found in the technical documentation.
To use this Information in a notification, I'd suggest to use the ttv functionality and the "predicted_sla_violation" or "macro_predicted_violation" Attribute.
