There are 4 types of change request in SAP
- Customizing Change Request
- Workbench Change
- Transport Of Copies
- Relocation of Objects
Customizing Change Request – This type or request is used to save changes made to client-specific data or objects. Most customizations done by functional consultants are client-specific and uses Customizing Change Request.
Workbench Request – is to save cross-client Objects and repository objects. Examples are tables, ABAP programs and other ABAP repository objects.
Transport of copies – When a change request is released, it moves to quality and then to production system. Transport of copies will be used when you want to move changes to a specified system and no further; for example we want to move changes to quality system but don’t intend to move to production system. This is useful in agile development wherein you quickly want to test the changes, but the entire project is still not completed and undergoing development.
Relocation of Objects – Use this type of transport system when you want to develop objects in another system on a temporary basis. For example you want to development in Sandbox system and later move to Development system.
