Using Approval Procedures 
You can use approval procedures to control the approval process for requests for change. In an organization, certain processes must be approved by responsible persons before they can be finalized. For example, a request for change 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 request for change, see the Approvals assignment block of the respective request for change.
Integration
You can control approval procedures using rule policies. For more information, see Using Rule Policies.

Features
In the header data of the request for change, 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 request for change 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 request for change 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 requests for change awaiting approval that are assigned to you.
You can use workflow functions for the request for change approval process so that approvers are informed when requests for change should be approved.
Activities
A service employee creates a request for change and the change manager classifies it, for example, as a normal change.
The change manager checks the request and releases it for approval. The request for change has the status Awaiting Approval. The system thus starts the approval procedure.
As soon as all approval steps have been completed, the request for change has the status Approved and the change documents for the request for change are generated.
