Oracle Assets uses the Account Generator to generate accounting
flexfield combinations for journal entries. The Account Generator
allows you to designate a specific source for each segment in the
account for which Oracle Assets creates a journal entry.Using the default
assignments, it creates journal entries using the balancing segment from
the distribution line in the Assignments window and the account
segment from the asset category or book, depending on the account
type. The Account Generator gets the other segments from the default
segment values you entered for the book.
