Diagnosis
When the system copies changes, it calculates the differences betweenthe initial ABAP source code and the final ABAP source code in thesource system (here &V2&). The system then attempts to add this deltato the initial source code in the local system (&V1&). If the initialsource code is the same, as it is in this case, the addition of thedelta in the local system (&V1&) results in the same final ABAP sourcecode as in the source system (here &V2&).
