I have a requirement to populate the line DFF with Header DFF values. I have two fields (Attribute1, Attribute2) at header level. Once i go to 'Cash and Other Expenses' screen, I will click on 'Details' button. Here i have two fields (attribute1, attribute2) at Line level. These two fields should be populated with header level dff values for all the lines.
Please guide me how can i achieve this requirement.
1. Find out the underlying VO of the Line details.
2. Extend the Controller of 'Cash and Other Expenses' UI.
3. Get a handle to the Header view object, ExpenseReportHeadersVO and retrieve the Header DFF values.
4. Set those values to the LineVO's attribute fields.
