Hi i have a pricebook called "test pricebook" for this pricebook will it allow the duplicate pricebook entries if i try to added through apex class .please help me will duplicate entries are possible for a pricebook

Hi everyone!
I am trying to set an object ownership to a queue of users. It is "kind of" working, but the users from the queue are not getting notified that a new object has been assigned to them.

my snippet code so far:

if (Trigger.isBefore){
	 Group queue = [SELECT Id FROM Group WHERE Name = 'IMP_Developer Queue' and Type='Queue'];
	 Trigger.new[i].OwnerID = queue.id;
}

The ownership is being set correctly. Is there a way to enforce the email sending for the queue users?

Best Regards!
