Editing Registered Source System Details
There may be times when source system details change. You can edit the source system details as needed. Keep in mind that once added, you should not modify the source system type.

In the Tasks pane, select Source System.
Select the source system.
Edit the source system details or ODI details as necessary.
Click Save.
If you make metadata changes in source system like adding new segment or chartfield values or hierarchies, you must initialize the source system.
