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 screens as a display-only value.

* If you are going to have many user formula columns, you may find it advantageous to create a package with your customer prefix, and then include all the functions within that package. This keeps all your work together in one place.

* It is important to ensure that a public synonym is created and grants made to the P2K_USER or users will get unexpected results in the screens where you may be using them.
* User Formula Columns should not be included in [ISPY] set up of PA Types.

In this example it is desired to have a column showing the value of a statistic called STAT-PA-DAYS (seen on [IEST]) for an employee. By reviewing the [ERD|ERD-HR01] 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.

The two slashes are an indicator to SQL to execute the lines preceding.
The creation of a Public Synonym means that users other than P2K (the schema owner) will have access to the function. The grant of the execute privilege is required so that other users (other than P2K) will be able to execute this. All users of the application must have the [P2K_USER] role granted in [IMUS] or [IMUR].

!!Table Cacheing (IMTD)
Note that once the field has been added to the table, you will not normally see this new field right away as this information is relatively static and the application's caching logic will not pick it up. To see the field right away, you can go to the [IMTD] screen for the [P2K_AM_COLUMN_DETAILS] table and press the ~[Clear Table Cache] button.
%%information
Note that once the field has been added to the table, you will not see this new field right away as this information is key to the application and thus will only be picked up on an instance restart.
