SAP Solution Manager – Change Request Management
Change Request Management in SAP Solution Manager is a process to track all the development/Configuration activities. Without SAP Solution Manager, we usually use a document manager system like MS sharepoint to manage and trace all the project document. But there is no tool to manage the change request status. That is to say, all the business partners related to a request cannot know the status of it unless he is notifies by an email. With Change Request Management, every one can easy find the status of it and all the related document easily. Below diagram shows the whole process.
There are two documents in each process. One is change request and another one is change document. These document reuse SAP CRM service order transaction and can be maintained by using transaction CRMD_ORDER.
Change request is a document used to maintain general description, business partners and IBase component. IBase component is which system you want to perform your changes. These system is customized for SAP Solution Manager -> Basic Settings -> SAP Solution Manager System -> Service Desk -> iBase. Once the change request is approved by the approver, a change document will be created automatically.
Developer use change document to create transport in the destination system. Once the request is successfully tested. All the transports will also be release through change document.
