SAP system present in customer environment is COPY of original system which is at SAP itself. That means all the objects present in customer environment are copy of the object originally created in SAP environment.

So, If we modify copy of object then it is called as REPAIR and ASSIGNED to development task repair. Repair of object is ALSO called as modification.

Whereas if we modify object in it's original system where it is actually created may it be SAP system or the objects created by customer in customer environment. Then such CHANGES is called as corrections and assigned to task Development/Correction.
