So therefore the use or advantage of External LOV is if we want a list of values to be used for other pages in the project then we can create External LOV region and we can use the created region in any pages of the project.
Steps to create External LOV in oaf are follows:
Step1: Create Workspace, project , AM and create one page assign AM to the page give page title and window title.
For example :
workspace name : externlallov
Project Name : ExternallovPRJ
package name : externallov.oracle.apps.po.externallovprj.webui
AM name : ExternallovAM
AM Package name: externallov.oracle.apps.po.externallovprj.server
Step2: Right Click on the project select new as shown in the below picture.
After selecting new option we will see a gallery window in that extract web tier in categories select OA Components and then select Region in items list.
After selecting region click on ok button so that a window will get open in that
Name : Give any user defined name
Package: Select the proper package of the project.
Style : select style as List of values.
Now one .xml region will be created under webui.
Step3: Create on VO under the lov package for example select the package name as follows:
VO Name is : externalLOVVO
Query in the lov is :-
SELECT FULL_NAME FROM PER_ALL_PEOPLE_F
Step4: Attach VO to the AM.
Step5: Under the region create one item and item style as Message LOV input. In previous lesson we already seen how the Message LOV input item structure look like.
The below image shows how the Application Navigator and page structure of the project looks like:
Step6: Under the Message LOV input region create on table region using wizard. In the table region select the proper package name and then as we attached our VO to the AM it will display our LOVVO so select that VO and therefore a table region will be created with one item under it.
Step7: Select the Message LOV input item and in the Property Inspector of Message LOV input select External LOV as shown in the below figure:
