Rather than importing to another ICS instance, we are going to apply a change that is simple to spot and then import the integration back into the same environment. In the rest of this section, we are going to make the changes to the integration you have already downloaded.

When making changes this way, we should think of it as opening up a black box. Oracle makes no guarantees about the content and structure of the .iar files. They do recognize that, at times, a desktop application such as JDeveloper may be better suited to performing the development of very complex mappings and transformations; editing this way can be achieved because ICS has been built making use of industry standards such as XSL. To help in these cases, Oracle have put into the files XML comments such as:

< -User Editing allowed BELOW this line - DO NOT DELETE
  THIS LINE-->

So, you can see where changes may be applied, but we would advise being careful before making changes...
