Derived columns can be added to tables, to further extend their utility, deriving their value from a PL/SQL function in the data base. This allows the field to be displayed on other screens as a display-only value.

The function must be defined in the data base as a PL/SQL function. The PL/SQL function must receive exactly one parameter: the ID of the record from the table the field is associated to; And the function must return a value (or NULL) of the type that is expected by the screen.

In this example it is desired to have a column showing the value of a statistic called (seen on [IMST]) for an employee. By reviewing the [ERD|ERD-HR1] for the [P2K_HR_STATISTICS] table we can see that the record is identifiable as an intersection between [EEM_ID] (The ID from [P2K_HR_EMPLOYMENTS]) and [DSC_ID] (The ID from [P2K_CM_STATISTIC_COMPONENTS]). As we know the specific statistic code we will always want, we can determine that the variable element here is the employment record ID.

Once we have the function defined and working, we can extend the table (in our example [P2K_HR_EMPLOYMENTS]) to include this User Formula Column. This is done in the [IMCD] screen by adding a new co9lumn with the following fields filled in:
;[Sequence]:It is recommended that you start your sequencing at 9999 and work down, so as to not collide with High Line provided sequence numbers
