OA Framework - Overview
• Oracle Applications Framework (OAF) is the Oracle
Applications development and deployment platform
for HTML-based business applications
– UIs/Forms for iProcurement, iSupplier, iExpense etc
• 100% Java & XML based
– OA Framework is J2EE based and features several
industry standards such as XML, HTML, Java, JSP, SQL
and Web Services
• Oracle 9i JDeveloper For OA extension
– Design-time extension to Oracle9i JDeveloper is called
Oracle Applications Extension (OA Extension)


OA Framework - Overview ..contd

• Advantages
– Scalable
– Personalizable
– Extensible
• Versions
– First released in 11.5.7
– Became extensible with 11.5.10,
or patched 11.5.9


OA Framework Characteristics

• Declarative and Rapid application development
• Consistent and Compelling UI
• Built-in durable Personalization
• Extensible UI and business logic
• J2EE based, Java and XML
• Based on MVC architecture

UIX Repository

OA Controller 11i Data


Model View Controller
• Model
– Data Controller

• View
– User Interface
• Controller
Model View
– Code
• MVC architecture is a component-based design pattern with
interfaces between the Model, View, and Controller.
• Separates core business model functionality from the
presentation and control logic that uses this functionality
• Allows multiple views to share the same enterprise data
model


OAF and MVC

• View – Common UIX-based HTML
components used throughout

Workflow
Apply Model
1. Controller delegates data
processing to Model
2. Determines next page View
3. Invokes View to present the
next page to user


OAF Page


Personalization & Extension
• Personalization
– Declaratively tailoring UI look-and-feel, layout or visibility of built-in
content to suit a business need or a user preference
• Change the prompt for a field and other text on a page
• Set whether a field or region is visible
• Reorder the fields or components on a page
• Restrict the data that a user can access etc.
– Use the Personalization Framework
• Extension
– Extending the functionality of an application:
• Adding new content or business logic
• Extending/overriding existing business logic
– Use Oracle9i JDeveloper


Personalization

• No development tool needed
• Personalizations are overlaid on top of
base product metadata at runtime
• Durable – Survive upgrades and patches
• Admin personalizations available on any Personalization
component Personalization

Personalization
Definition
• User personalizations on tables/inquiries
Definition

• Can implement personalizations on test
system Base Product
Page Definition
• Personalization feedback is immediate
• Administrator can easily enable/disable
personalizations


Personalization Levels
• Admin Level Personalization
– Site, Organization, Responsibility
• Single view at each level
• User Level Personalization
– User Views
• Several views per User Personalization
• Each level overlays the levels Personalization

Personalization Profile Options

• Personalize Self-Service Defn
• Disable Self-Service Personal
• FND: Personalization Region Link Enabled
• FND: Diagnostics

• Refer to Metalink Note:275876.1 for exhaustive list
of OAF Profile options


OAF – New Responsibility
• Functional Administrator
– Sysadmin of Personalization
– Deploying Personalizations
– Import and Export Personalizations
– A Real Life saver when dealing with Personalizations


Extensibility

• Extending & Creating Business Objects
– New Page
– New Attribute
– Extend/Override defaults and validations
– New business logic
• Extension is achieved using the BC4J components:
– Entity Objects (EO)
– View Objects (VO)
– Application Modules (AM)


Onion Ring
OA Framework applications layers
• OA Framework applications can be abstracted into
a series of concentric layers, like an onion.
• Each layer only “knows”
about the layers below it.
• This encapsulation allows
OA
Controllers

reuse at any of the layer Application
Modules
boundaries. View
Objects

Entity
dataflow up stack (pull) Objects

dataflow down stack (push) DB


Entity Object (EO)

• Data interface, not Application interface
• Encapsulates business rules
• Each table can have at most one entity object
• EO instance is associated with a row from the
database table
• Handles transactional details
• Automatically implements DML operations
• Resides in
– <company>.oracle.apps.<cust_top>.xxx.schema.server pacakge


View Object (VO)

• Application interface, not data interface
• Encapsulates database queries
• Provides access to EO’s
• Two types
– SQL based
– EO based
• Resides in
– <company>.oracle.apps.<cust_top>.xxx.server pacakge


Application Module (AM)

• Application Module is container for VOs
• Establishes the transaction context for the related UI
pages
• Every page must have a root application module
– Oracle.apps.fnd.framework.server.OAApplicationModule
• Resides in
– <company>.oracle.apps.<cust_top>.xxx.server pacakge


Case Study of Logitech Inc.,
• Development Tool used
– Oracle 9i JDeveloper Version 9.0.3.5
• Customizations
– iSupplier Customization
• PO Acknowledgement and Notification
• ASN Update to PO
– Special Pricing Approval and Processes
• New OAF Pages in association with Workflow Developed


iSupplier Customization - iSupplier PO Acknowledgement

Supplier
Acknowledgment
Logitech - Case Study

of PO

Supplier View of the
Purchase Order


iSupplier Customization - iSupplier ASN Update to PO

• ASNs are created through iSupplier
– Automatically update the PO Shipment DFF for Shipment
Date and Status
– Automatically Re-Calculate Promised Date, based on

Actual Ship Date.
– Automatically reset the Promised Date to the previous
value in the event of ASN Cancellation
– PO Shipment DFF updates should not cause a PO Revision.
– PO Shipment DFF updates should not require re-approval.
– PO Shipment DFF updates will be visible in iSupplier


Special Pricing
• Business requirement
– Create special prices for selected customers and groups of
customers.
Logitech Inc - Case Study

– Flexibility to set promotional limits.
– Facility to choose Items for which the Special pricing is
applied.
– Define the Date ranges for the Special Pricing.


Special Pricing

the Promo request will go through the approval Process.
After approval process this will be applied as requested


Lessons Learned and Development Tips
• Customization/Development Estimates
• FND: Diagonstics
• Functional Administrator
• Defects in Standard packages (raise tar)
• Concurrent program for bouncing the apache server
• Use JDeveloper BC4J wizards to extend and create new Business Objects
• Always extend the object, never start with a copy of an object .
• Use the substitution mechanism to let OA Framework start using the
extended version of the object
• Use “About this Page” link to get all the information related to the page
– Get page name and location
– Version numbers
– BC4J object names, etc.
• Please refer to chapter 8 of OAF Developer guide for Coding Standards
