Using the Debug Application
Another option that you might consider for understanding a JD Edwards EnterpriseOne application is to run a JD Edwards EnterpriseOne debugger. You can run the Event Rules Debugger to obtain named event rule and table event rule information for a JD Edwards EnterpriseOne application. You can use Microsoft Visual C++ to debug business functions that are written in C. You can use these two tools together.
See "Understanding the Event Rules Debugger" in the JD Edwards EnterpriseOne Tools Event Rules Guide.
