In the Analytics you need first filter the service item and then you will get the fields. 

Oh wow thank you. I have missed this somehow.
Its not perfect, but better than nothing.

Now they need to implement the custom fields also for the Group By function as I now need to add 30 different charts for 30 different Service Items with the same custom action names

ya and I did som tests not all fields can be used in the report. :( 

Did this function get removed? I’m trying to do something similar, but even after filtering by the specific service item, I don’t get any option to select the custom fields inside of it. I’ve tried with several of our service requests and always get the same result.

 

No, it still works for me

Thanks for confirming. I’ve placed a ticket with support.
