Identifying Events
To view the execution flow in full detail, use the system logging functions. Set Debug Level (36.24.3.5) lets you set the level of detail displayed in the system ctlog file. You can display full business code, including parameter values and database queries.
When logging is enabled, you can run the function you want to customize, and then display the execution flow in ctlog. The log displays the business methods used in the function and how they are implemented.
See Set Debug Level.
