Question: Expalin about FieldFormula in PeopleCode?

Answer: The FieldFormula event is not currently used. Because FieldFormula PeopleCode initiates in many different contexts and triggers PeopleCode on every field on every row in the component buffer, it can seriously degrade application performance. Use RowInit and FieldChange events rather than FieldFormula.
If a field value is changed, whether through PeopleCode or by a user, the IsChanged property for the row is usually set to True. However, if a value is set in FieldDefault or FieldFormula, the row is not marked as changed. At save time, all newly inserted and changed rows are written to the database. All newly inserted but not changed rows are not written to the database.
As a matter of convention, FieldFormula is now often used in FUNCLIB_ (function library) record definitions to store shared functions. However, you can store shared functions in any PeopleCode event. FieldFormula PeopleCode is only associated with record fields.
