Only current Assignment Group should have access to update Assignment Group field on Incident form

Only current Assignment Groups should have access to update Assignment Group field on Incident form.

Please help! I tried business rule but able to select groups which the user is member of but unable to restrict group change if user is not member of group.

Suppose: Incident 123 is assigned to Network group only users from Network must be able to update assignment group of Incident. For all other users there must be an error message.

Thanks in advance!

Build you ACL condition as 

Ok...You will have to write script in the ACL as below

answer = false;

if (current.assignment_group!='' && (gs.getuser().isMemberOf(current.assignment_group.toString()) || gs.getuser().isMemberOf('ServiceDesk') || gs.getuser().isMemberOf('Network')))

{

answer = true;

}

thanks so much i was able to get it working with small modification. (Removed ".toString()" for 

answer = false;

if (current.assignment_group!=' ' && (gs.getUser().isMemberOf(current.assignment_group) || gs.getUser().isMemberOf('Service Desk') || gs.getUser().isMemberOf('Network')))
{
answer = true;
}

thanks!

To keep it editable if assignment group is blank, replace with below script

answer = false;

if (current.assignment_group==' ' || gs.getUser().isMemberOf(current.assignment_group) || gs.getUser().isMemberOf('Service Desk') || gs.getUser().isMemberOf('Network'))
{
answer = true;
}

Replace with below code

answer = false;

if (current.assignment_group==' ' || gs.getUser().isMemberOf(current.assignment_group) || gs.getUser().isMemberOf('Service Desk') || gs.getUser().isMemberOf('Network'))
{
answer = true;
}

Please mark my response correct if it works
