Specify package name
E.g: Name:ImportcsvAM
Press Next Button
Step 2: Make sure in Data Model your Application Module is appearing and Press Button Next
Step 3:Press Button Next
Step 4: Check the Generate Java File(s) checkbox in Application Module Class: ImportcsvAMImpl to generate the ImportcsvAMImpl java class. (It is already checked by default.)

Right Click on Project -->New -->Business Tier -->ADF Business Components -->Entity Object --> Press OK button.
New Window will appear to you which contains 6 steps
Step 1: Specify the Entity Object Name
E.g : ImportcsvEO
Specify Package or Path oracle.apps.fnd.schema
Select Database object
E.g: XX_IMPORT_CSV_DATA
Press Button Next
Step 2: Press Button Next
Step 3: Press Button Next
Now popup message will appear front of you as we did not define any primary key. Therefore, it will consider ROWID as primary key. Press Yes

Step 2: In Available list go to Oracle.apps.fnd.schema and shuffle ImportcsvEO to selected list
Press Button Next
Step 3: Shuffle the required columns to selected list and Press Button Next
Step 4: Press Button Next
Step 5: Press Button Next
Step 6: Press Button Next
Step 7: Check the checkbox View Row Class: ImportcsvVORowImpl for both the Generate Java File and Accessors checkbox
Step 8: In Finish window, Press Finish Button.
Linking the view object to the application
module(VO to AM)

module, perform the following steps:
- In the Application Navigator tab, double-click the ImportcsvAM
- In the Application Module Editor select the Data Model node.
- Expand the oracle.apps.fnd.server package, and click on the ImportcsvVO view object.
- Shift the ImportcsvVO from Available View Objects: to Data Model: by clicking on the > button
Create Page
