OAF VO Extension : How to add new Column in the Expense Report Summary Home Page

OAF VO Extension : How to add new Column in the Expense Report Summary Home Page

In this post , we will do View Object VO extension in Oracle Application OAF web pages. first of all , we will discuss the need of the VO extension in OAF. When we have an requirement to display some more attributes or fields in the OAF page then we do VO extension to meet this requirement. We all know that , We see the data in the OAF page through View Objects(VO) and in a single page can have more then 1 View Objects(VO). First of all , we need to find out that , in which Standard View object , we need to add new Fields in OAF Page. Then we do view Extension , to add this new field in the View Object and then display this new Field in the OAF page through Personalizations.
 

VO Extension Steps:-

1.Indentify that Which VO we need to Extend
2. Download the VO from Oracle Java_Top Location to Your Local Desktop under My Projects folder of Your JDev setup.
3.Then We create New view Object(VO) which extends the Standard View Object.
4.Then We substitute the New Custom View Object with the Standard View Object.
5.Then we upload the New Custom View Object to Oracle Java_Top Location.
6.Then we Register the New View Object in the Oracle application Through XML Importer script.
8.After Import/Register , We add the new field in the OAF page through Personalization and then give reference in this Field for the New Custom View Object(VO).
 

OAF VO Extension Example: How to add new Column in the Expense Report Summary Home Page

 
Step1:- First Go to your OAF page in the application , in which you will do View Object Extension.
This is the Page in which we will do View Extension. Here I want to display the DFF attribute5 in this Track Submitted Expense Reports Status Window.

Step2:- To see the Properties of this Page and to know which View Object is working behind this Page. for this we need to go to 'About this Page' in the Bottom of the Page.
 
 
 
Step3:- Click on the Expand All option and in the Controller Section you can see the Controller Name

Step6:-
 
 Now you get to know that where is your Standard View Object is Placed in the Oracle application Under Java_Top.

Then you Need to go to Server Under Java_Top then Under Java_Top follow the same path 'oracle/apps/ap/oie/webui/' and copy the 'TrackExpesneReportsVO' from Server to your Local Desktop.

One Important Thing.

You need to create the same path in your JDev folder under' 'jdevhome'
Under JdevHome there is MyProjects' folder under this folder you have to Create same folder structure like oracle/apps/ap/oie/server/' and then this copied file 'TrackExpesneReportsVO' in this Location.

The rule is you have to create same folder structure like the Folder Structure created for The Standard Controller in the Application server Java_Top.

have one seeded page where there is LOV called Category , but when LOV is open there is Category as well as Description , so here my question goes:

1. How to make description as default search , so whenever user on lov tried to search by description the LOV region should search by description.
