What are clones?

Standard SAP offers lot of out-of-the-box functions and reports. But in many cases the standard report only offers 95%. What to do? In many cases developers copy the standard SAP program to Z copy and add the needed 5%. When upgrading the system to higher version or when applying support packages or OSS notes, the Z clone will not be upgraded to latest version. Maybe the clone needs updates as well, or can be deleted now after upgrade (if SAP added the missing 5%).

The clone finder tool is able to find the clones made in the past.
