Configure automatic status change for approvals
You can configure the Approvals feature to automatically change status according to the percentage of approvers who accept or reject an object in the Approval cycle.
In triggerswebplatform.xml, the EvaluateApprovalTrigger
				trigger defines when an object in the Approval cycle changes from its original
					open status to a final status, such as
					approved or rejected.
Note: You can set the 
			validation parameter
				trigger to any number from 0 to 1. This value sets the percentage of approvers
				required for changing the object's status to approved. Suppose you set validation to 0.75. That  establishes
				the percentage of approvals required for an object in the Approval cycle to change
				to the approved status as 75 percent. If less than 75 percent of
				the assigned approvers approve of the object, the Approval changes to
					rejected.
Note: It is not necessary for all assigned
					approvers to complete the approval to trigger the automatic status
					change.
			Tip: You can also comment out the trigger to disable the automatic status change of
				objects with an Approval status.
