Please clarify what exactly do you want to achieve.
You can get the details from CTM:Support Group form.
use Support Group Association form for your concern.
I have checked with the mentioned form, is it available in ITSM suite 7.1 as could not found it?
Do you have a "CTM:Support Group" form with a tab with the list of people members of this group?
If so, open the form with developer Studio (or Administrator) and look at the qualification of the table.
Kindly use following steps:
1) On People Form Quick Links Section Choose Advanced Search Option.
2) There you have option to search the People profiles support group wise.
Just put the required qualification & search records.
On support group association form we will get support group associated to that person only. And if we want to check how many users are there in that support group then we have to use support group form.. Right ?
For More details please open below form and enter support group id, you will get what you are expecting...
