Using Approval Procedures 
You can use approval procedures to control the approval process for change requests. In an organization, certain processes must be approved by responsible persons before they can be finalized. For example, a change request must first be approved before an urgent or normal change can be made.
Approval procedures can be edited manually or integrated into the workflow. For all information relevant to the approval of a change request, see the Approvals assignment block of the respective change request.

Features
In the header data of the change request, you assign the approval procedure. By default, the approval procedure CR Approval Procedure is suggested for use.
The following functions are available in the Approvals assignment block:
You can monitor the approval steps and the corresponding information. For example, you can see which business partner has approved the respective step and when the approval took place.
The change manager is entered as the approver by default. You can also add other approvers.
The parties involved in the change request enter their approval activities. Here, the options Approved, Not Relevant, and Rejected are available. The approvers can add additional comments to the activity, for example, explanations of a rejection.
As long as the status of the change request has not been set to Approved, you can add additional or remove existing approval steps and approvers.
In the Change Management work center, you see the change requests awaiting approval that are assigned to you.
You can use workflow functions for the change request approval process so that approvers are informed when change requests should be approved.
Activities
A service employee creates a change request and the change manager classifies it, for example, as a normal change.
The change manager checks the request and releases it for approval. The change request has the status Awaiting Approval. The system thus starts the approval procedure.
As soon as all approval steps have been completed, the change request has the status Approved and the change documents for the change request are generated.
