A basic requirement in most implementations is displaying company logo. This article shows how to achieve it in Application Express.

Requirement:
Display Apps2Fusion logo on Person Details application http://apex.oracle.com/pls/otn/f?p=62577. To take step forward, I want to make the image clickable to redirect user to apps2fusion website in separate window.

My previous article on Nested application module showed extending root AM by attaching nested AM programmatically. In this article I'll show another approach to achieve same objective. My objective is to add custom logic to print "Requisition Header Id" in console when "Add to Cart" button is pressed during requisition creation in iProcurement. Some details of 'About this Page' for Non-Catalog Request page.

Page Name: NonCatalogRequestPG
Controller: NonCatalogRequestCO
AM: RequisitionAM

You have seen how APEX URL carries parameters when branched from one page to another. Session State Protection can prevent users from tampering URL, but it doesn't help much in not showing parameters in URL. Imagine how it could be a security vulnerability when you pass sensitive information like passwords, ssn etc.

In one of my old articles on OA Framework extension, I briefly mentioned about Nested Application modules. Today I will explain how Nested Application module can be used. Nested AM is an application module which is under the scope of root application module. Root application module is the AM attached to top region of the page during design time. It maintains the session state and retention level for requests between client and server.

Root AM can contain one or more nested AMs which can themselves nest children to any arbitrary level. In this scenario, the root AM has access to all the data/objects held by its children, and all children participate in the same transaction established by the root.

Following are the questions can often come to mind when dealing with Business Event Subscriptions
1. What is the difference between raising a business event from PL/SQL or from Java
2. Why you should not raise a Business Event from OA Framework using a JDBC call to "wf_event.raise"
3. The subscription does not fire in real time, even though business subscription phase is less than 99

Let us deal with these questions one by one.

Oracle AIM Project Management Methodology provides the basic framework in the Implementation of Oracle E-Business Suite to Clients by the Implementers. I have prepared this document based on my Project Management experiences and this may not be a 100% fool proof method. But I tried to give importance to the basics of AIM Methodology which will help the freshers, Intermediate and average consultants to gain the basic understanding and knowledge of Oracle AIM Methodology and grow up in their career.

By now you should be having a fair idea of high usability of Oracle Application Express a.k.a APEX with its easy navigation between pages using column links, branches, breadcrumbs, navigation tabs, etc. For example, in Person Details application you can click on edit icon on a person row which takes you to Edit page for editing and saving that person details. The navigation here is done through column link by setting P4_PERSON_ID page item on Edit page (4) with Person_Id column value. If you observe closely parameters appear on URL string, it looks similar to

http://apex.oracle.com/pls/otn/f?p=62577:4:7632245014057279::NO::P4_PERSON_ID:241

where 7632245014057279 is my session id, P4_PERSON_ID is page item and 241 is page item value.

Authorization is a process of determining whether an authenticated/identified person is permitted to access a resource or do an operation. It is based on set of privileges or roles assigned to the user. For Example, In Oracle database, Administrator have privilege to schedule jobs, while an user cannot.

How is Authorization different from Authentication?
Often Authentication and Authorization work together. In other words, Authorization follows Authentication.

Authentication determines Who are you?
Authorization determines What you are allowed to do?

In this article we will undertake a simple example for AME customization in iRecruitment. This example pertains to Vacancy creation process in iRecruitment.

In the last three AME articles we learnt
1. Basics of AME
2. How SSHR is attached to HRSSA Workflow and AME
3. How to create FND User for AME with necessary RBAC

This example has been purposely kept very simple to show you the end to end process involved in setting up Custom Logic for AME in eBusiness Suite. At the end of this example, you will find a link to see the video demo explaining how these steps are implemented in real-time. Do not miss out the video link at the end of this article if this is first time you are trying to customize AME.
