So on the Case page it would look like this:
and when they clicked the 'Take Next Ticket' link it would return the next ticket by SLA and priority, and automatically assigns the user as the owner of the Case. Then once they close the case and click the 'Take Next Ticket' link it will all repeat over and over. Ensuring that no one has Cases waiting to in their personal Queues and that the oldest/highest priority gets handled first.
Custom Setting Setup:
Example Items:
| Name | Priority(1-10) | SLA(min) |
| HighPriorityQueue | 10 | 12 |
| AnotherQueueName | 5 | 24 |
| LowPriorityQueue | 1 | 36 |
Formula Field Setup:
The field needs to be a number and the formula to calculate the age of the Case in mins:
Now the VF page:
The page itself will be blank, unless you want to show errors if anything fails, like no more tickets in the Queues that the rep belongs to.
<apex:page standardController="Case" extensions="TakeNextTicketCon" standardStylesheets="false" tabstyle="Case" action="{!TakeNextTicket}">
<style>
#messageWrap{width:50%; margin:auto; font-size:15px;}
#linkWrap{text-align:center;}
ul li{color:red; text-decoration:none; list-style:none; padding:0px; margin:0; text-align:center;}
</style>
<apex:form >
<div id="messageWrap">
<apex:messages id="messagesblock" />
</div>
<div id="linkWrap">
<apex:outputlink value="/{!Case.id}">Go Back</apex:outputlink>
|
<apex:commandLink action="{!TakeNextTicket}">Take-Next-Ticket</apex:commandLink>
</div>
</apex:form>
</apex:page>
Now the fun stuff, the Classes. In mine i split the classes up into the main controller (TakeNextTicketCon.cls) and a helper class (TakeNextTicketHelper.cls) and then finally the test Class (TakeNextTicketHelper). I tired to set up the classes so that all the info and action methods are in the Main class, and the everything else is in the helper. It was difficult to get the info required for this due to the way that salesforce has the Queue's set up in the schema.
To get the Queues that a user belongs to for a particular sObject, you need to first query GroupMemeber where UserOrGroupId = User Id
GroupMember[] gm = [Select Id, GroupId From GroupMember where UserOrGroupId =:sInUserId limit 50];
Then you need to take that list and convert it to a string list of GroupId's and use it to query the Group sObject where type = Queue and the id is in the list of id's that we just create from the GroupMemeber sObject.
Group[] g = [select id, Name from Group where Type = 'Queue' and id IN :lstInGroupId limit 50];
Then once you get that list and again convert it to a string list of Id's and use it in the next query of the QueueSobject where sobjectType = Case and QueueId is in the list of Group id's.
QueueSobject[] q = [Select Id, QueueId, Queue.Name From QueueSobject where SobjectType = 'Case' and QueueId IN:lstInGroupIdlimit 50];
fun right? If you look at the sObject in schema, you'll see why i did it that way, but you'll see another way to traverse the sObjects in an upcoming post on making the User/Queue edit more manageable. But lets take a look at the classes i used to power this little link of wonders, just note that I will not be explaining the classes, just showing them. If you need help understanding what or how I did something feel free to contact me and I will brake it down further.

The Test class i will leave up to you, in my org, we try to get as close to 100% coverage as possible, and i recommend the same for your org as well. If you don't, and just go for 75% coverage, you will find issues down the line with not being fully covered. Remember the rule of 75% coverage is an org standard not per class, so if a few classes bring the average down then you need to go back and fix old code. So its best to take the extra hour and try to get the most coverage as possible in the project you are working on.
Once all the classes are done, you'll still need to add it to the case as a link then add the link to the page layout.
Once you add it as a button/link on the case sObject it will be available to be added via the page-layout edit page.
