Running Case Assignment Rules From Apex

|Description||How to run case assignment rule from trigger|
Case assignment rules allow you to automatically route Cases to the appropriate users or queues. A Case assignment rule consists of multiple rule entries that define the conditions and order for assigning cases. You can create multiple rules (for example, a Standard rule and a Holiday rule), but only one rule can be "active" at a time.
From a standard UI, a user can trigger assignment rules by simply checking the "Assign using active assignment rules" checkbox under the Optional section. The problem arises when your app needs to insert the Case from Apex and wants to trigger assignment rules. Using this script, a Case will be inserted but assignment rules will not be triggered as there is no such field "Assign using active assignment rules" on Case.
