Action types are used to access data within the system based on the user and/or the level of security. The four action types available are:

i) Add: Add a new row to a table with a new high level key/primary key

ii) Update/Display: Either data can be updated or displayed with a high level key. To update data, insert a new row of data with an EFFDT greater than the date of the current row.

iii) Include History: Works the same as Update/Display but will allow the user review not only the current and future rows, but history rows as well.

iv) Correct History: View, change and insert rows of data regardless of effective date.
