Oracle Application Express (APEX) is increasingly being used to produce custom developments within Oracle E-Business Suite. I've posted previously about how to configure your custom applications to use E-Business Suite context for purposes such as foundation API's, MOAC security, profile values and such (using fnd_global.apps_initialize), however I've generally put in a note of warning that such techniques may not work with Human Resources Security. So here I will explain why that is, what you might be able to do to get around that. This assumes the Embedded PL/SQL Gateway (EPG) is being used.

First, let's recap how HR Security is implemented with E-Business Suite, taking People table as an example.
We have the base table per_all_people_f which is not secured (by VPD or otherwise). Built upon this are a set of secure views such as per_people_f which are queries from the base table however with a call to the API hr_security as follows.

per_people_f snippet

The key call in this code is to hr_security.show_person(...) which evaluates the users access to that person record based upon the security profile the user is currently using (the actual method for this depends on whether Cross Business Group security is in use).

I recently needed to use the LISTAGG function in a custom Oracle ODI interface. However to my dismay I found that ODI didn't recognise LISTAGG as an aggregate function (i.e. didn't add a GROUP BY clause to the SQL generated).

No Group By

After a bit of searching on Google I found I wasn't the only person to have hit this and found this blog post which explains a method for adding the function to the language in the ODI topology. I tried and failed - no matter what I did I couldn't get it to work.
So instead I tried a little trick I have used in the past for something simlar - to add a commented out aggregate function in the column source.

The WITH clause (or subquery factoring clause) is a very useful construct. It allows us to materialize the results of a SQL statement to use multiple times, without having to re-execute that statement. Here is an academic example of that in practice.

With demo As
 (Select * 
   From Employees e
  Where e.job_id = 'IT_PROG')
Select * From demo d, demo d_mgr
 Where d_mgr.employee_id = d.manager_id; 

It's very unlikely that we'd produce the above requirement as-is, however for the purposes of this demo it'll suffice.

One of the advantages of a Cloud BI solution is that it received regular updates and so is always "current" without the consumer having to do anything. 


The recent November 2015 refresh has provided a new, cleaner interface as well as a number of additional features.
