WriteToLog Next time you need to do some in-line PeopleCode debugging, rather than the traditional approach of using MessageBox, orWinMessage, consider using the PeopleCode WriteToLog function. To summarise, the WriteToLog function consists of two parameters: Log fence setting, I usually use %ApplicationLogFence_Error (1) to ensure it will write a log file The relevant text string to be written to the log file When called, it will write to a file called something like _.tracesql in the application server logs folder (where you would typically find other trace files). The thing I like best about this is that it is unobtrusive. It doesn't impact other users and it doesn't stop execution flow (nothing worse than a MessageBox in a loop that you have to click through 50 times!).
