WRITE
When Progress changes the contents of a record and validates it for a particular database table, Progress first fires all applicable WRITE triggers, then fires all applicable REPLICATION-WRITE triggers. Progress automatically validates a record when releasing it. You can also use the VALIDATE statement to explicitly validate a record. In either case, WRITE triggers execute before the validation occurs (so WRITE triggers can correct values and do more sophisticated validation). Progress might execute the WRITE triggers for a single record more than once before it writes the record to the database (if it validates the record more than once and you modify the record between validations).
