Can you share the steps you use to reassign tickets in bulk?
Currently its done as Select All -> Change the assigned group -> Reassign it to different group -> Save.
So we just want this to be restricted between some set of groups that bulk reassignments should not take place & can assign only one case at a time.
The reason I asked because this is not possible in Smart IT.
So you are doing it from mid tier with modify all operation which you can disable.
Go to Developer studio and open the form HPD:Help Desk.
Click on form and go to view properties.
Remove Modify All
Flush mid tier cache.
The requirement is to be implemented only for certain support groups & not the generic one for all.
