Reassigning Objects to Another Development Class 
You can move objects from one development class to another. For example, you can create and test ABAP programs in your local private object list (development class $TMP), and then reassign them to another development class for transport. To reassign an object:
The system asks you for the name of the new development class.
If the object was not previously assigned to a change request, you must specify one now.
The system adds the object to the change request and moves the object to the new development class.
To move several objects to the same object list, select them as a group and choose Development object
® Reassign. The system moves the entire group to the development class you specify.
