Hi @sonali bhagat, You can create a 'User Criteria' and add it to the 'Available for' related list on catalog item.
If you want to check the group membership, then you can create a system property to add the groups list and then check the advanced box to add your script.
answer = false;
if(gs.getUser().isMemberOf('group_property')){
answer = true;
}
Regards,
Sunil
