Using the PeopleCode Debugger
After the system is configured properly, using the PeopleCode debugger is just a matter of signing on to the PeopleSoft system and entering the PeopleCode Debugger mode in Application Designer.
Note:
You must use a unique user ID when you're performing PeopleCode debugging, as opposed to using a shared user ID, such as those that PeopleSoft delivers, for example QEDMO, PS, or VP1. Shared IDs are likely to be used by others that are connecting to the same test database, which can affect debugging.
