How do I filter (JQL) all service management issues in Jira?

Clemens Kleibusch

Hello community
There are already some holes in the JQL commands. But now I have come across one for which I have not found anything on the net:
How do I filter all service management issues in Jira?
I crawled through the reference fields and thought it should work with

request-channel-type is not EMPTY

But there are many hits in our software projects. For whatever reason.

Every idea is welcome. I don't want to list all (around 100) SM projects.

Thanks, Clemens

Hello @Clemens Kleibusch 

Do you able to make a request with : request-channel-type = Portal or similar value ?
That will show you all request that created via portal . 
Or you can also try a request  :
"Customer Request Type" is not empty or similar field on your instance
Hope this can help
