Date tracking in Oracle HRMS

Question

Hello,
in PER_ALL_ASSIGNMENTS_F AND PER_ALL_PEOPLE_F and other data tracked tables, is there any way to find out when a new record is going to be inserted and when an existing record is updated? For example when a job of a person is changed, a new assignment record is added. Similarly at what circumstances these date tracked tables are changed? Is there any document to find out a way to figure out?
Thanks a lot in advance.

Hi,
If I understand you correctly ypu want some npiece of code which does this checking for you and takes proper action.
There is a specific api DT_API which helps you do that.
I am posting a piece of code from that API (Spec from 11.5.10 instance)
dt_api.find_dt_upd_modes_and_dates
(  p_effective_date                in     date
  ,p_base_table_name               in     varchar2
  ,p_base_key_column               in     varchar2
  ,p_base_key_value                in     number
  ,p_correction                       out nocopy boolean
  ,p_update                           out nocopy boolean
  ,p_update_override                  out nocopy boolean
  ,p_update_change_insert             out nocopy boolean
  ,p_correction_start_date            out nocopy date
  ,p_correction_end_date              out nocopy date
  ,p_update_start_date                out nocopy date
  ,p_update_end_date                  out nocopy date
  ,p_override_start_date              out nocopy date
  ,p_override_end_date                out nocopy date
  ,p_upd_chg_start_date                out nocopy date
  ,p_upd_chg_end_date                  out nocopy date
  )Now there are numerous boolean variables and based on their values the action gets decoded.
For example if you want to check for a record started on 01-JAn-2012 and you want to check what will be mode on 01-SEP-2012 then
p_effective_date := '01-SEP-2012'
p_base_table_name := 'PER_ALL_PEOPLE_F'
p_base_key_column := 'PERSON_ID'
p_base_key_value := 1234
where 1234 is value of person_id.
IF ( p_update_override = TRUE OR p_update_change_insert = TRUE )
    THEN
        -- UPDATE_OVERRIDE
        gc_dt_ud_mode := gc_upd_override; -- UPDATE OVERRIDE
    END IF;
    IF (p_correction = TRUE )
    THEN
        -- CORRECTION
        gc_dt_ud_mode := gc_correction; -- Correction
    END IF;
    IF (p_update = TRUE )
    THEN
        -- UPDATE
        gc_dt_ud_mode := gc_update; -- UPDATE
    END IF;
