Can you use the "Close Alerts" Editor in SMARTView to close related alerts across all message channels?
With the Editor you would have to individually drag each MC into the Selection List. This is time consuming and also subject to maintenance if you create more Message Channels.
The best solution is within the CAF Global Logic or SMARTView Rule Logic where you can defined logic such as the following:
if left(s_mcname,8) = 'piPATROL' then rc = AlertsClose('','','','Object:')
This basically says if your event comes from a MC prefixed piPATROL then close any alert from any rule within any group within any message channel with a matching Object value.
