<font size="4"> </font><br>
<font color="#0000FF" face="Arial">A horse and a dog has some common features; having four legs, fur, a tail, and being able to pull a sled. Dog is not a subtype of a horse. So you should copy the horse object type to create a new "root" object type for dog (unless they are both defined as subtypes of e.g. mammal). However, a pony is a subtype of a horse, so you should create a subtype and definitely not make a copy.</font><br>
<font size="4"> </font><br>
<font color="#0000FF" face="Arial">In the same manner, even if, say application for vacation has some common features with application for a new pencil sharpener, they are completely unrelated. They may both support an interface for applications (which according to Shai Agassi should have one method: reject), but that is as close as they get. You create a copy. The problem is of course that in real life it is sometimes not that easy to determine whether it is a subtype or not, and which choice makes most sense can depend on your point of view.</font><br>

<font size="4">G'day Nat,</font><br>
<font size="4"> </font><br>
<font size="4">A copy is a static duplicate as at the time you perform the copy. All code will live inside the copy.</font><br>
<font size="4"> </font><br>
<font size="4">A subtype is a more complex OO concept. In this case it is not a copy, but an extensible reference to the parent. All the parents code (other than the definition of the key) remains in the parent objects program and the subtype simply access it from the there. Any new methods or attributes code will be in the subtype's program. This way if SAP provides fixes or extensions to the original object your subtype INSTANTLY has access to those fixes or extensions. </font><br>
<font size="4"> </font><br>
<font size="4">Subtyping is way sexier than copying!</font><br>

What is the difference of creating a subtype of a BO VS copying a BO?<br>
