1. Create a Search Page to Create a page please go through the following link

https://blogs.oracle.com/prajkumar/entry/create_oaf_search_page

2. Implement a Delete in your SearchEOImpl Class

public void remove()
{ super.remove();
} // end remove()

3. Create a Delete Image

Select ResultsTable right click > New > Item

Set following properties for New Item

ID – DeleteAction

Item Style – image

Image URI – deleteicon_enabled.gif

Atribute Set -- /oracle/apps/fnd/attributesets/Buttons/Delete

Prompt -- Delete

Additional Text – Delete record action enabled

Height – 24

Width – 24

Action Type – fireAction

Event – delete

Submit – True

Select Parameter Properties define parameter name as Column1 and whose value is

${oa.SearchVO1.Column1}

Select Parameter Properties define parameter name as Column2 and whose value is

${oa.SearchVO1.Column2}

Select OK button to create your request parameters

4. Add Page Controller

Add a New Contoller for SearchPG

Name – SearchCO

Package -- prajkumar.oracle.apps.fnd.searchdemo.webui

Implement Delete Action

5. Add deleteRecord() method to SearchAMImpl

import oracle.apps.fnd.framework.OAViewObject;
import oracle.apps.fnd.framework.server.OAApplicationModuleImpl;
import oracle.jbo.domain.Number;
import oracle.apps.fnd.framework.server.OAViewObjectImpl;
import oracle.jbo.RowSetIterator;
...

public void deleteRecord(String Column1)
{ OAViewObject vo = (OAViewObject)getSearchVO1();
SearchVORowImpl row = null;

int fetchedRowCount = vo.getFetchedRowCount();

RowSetIterator deleteIter = vo.createRowSetIterator("deleteIter");
if (fetchedRowCount > 0)
{ deleteIter.setRangeStart(0);
     deleteIter.setRangeSize(fetchedRowCount);
     for (int i = 0; i < fetchedRowCount; i++)
    {
      row = (SearchVORowImpl)deleteIter.getRowAtRangeIndex(i);
      row.remove();
      getTransaction().commit();
      break;
    }
}
deleteIter.closeRowSetIterator();
} // end deleteRecord

Note – Create Standard FND Messages DELETE_RECORD_WARN and DELETE_CONFIRM

6. Add DeleteSelection Handler Code to SearchCO.processFormRequest()

import com.sun.java.util.collections.HashMap;
import oracle.apps.fnd.framework.webui.OADialogPage;
import oracle.apps.fnd.framework.webui.OAWebBeanConstants;
import oracle.apps.fnd.common.MessageToken;
import oracle.apps.fnd.framework.OAException;
import oracle.apps.fnd.framework.webui.OAWebBeanConstants;
import oracle.apps.fnd.framework.OARow;
import oracle.apps.fnd.framework.OAApplicationModule;
...

OAApplicationModule am = pageContext.getApplicationModule(webBean);
OAViewObject vo =(OAViewObject)am.findViewObject("SearchVO1");

String rowRef =
pageContext.getParameter(OAWebBeanConstants.EVENT_SOURCE_ROW_REFERENCE);

OARow row = (OARow)am.findRowByRef(rowRef);

if ("delete".equals(pageContext.getParameter(EVENT_PARAM)))
{
String Column1 = (String)row.getAttribute("Column1");
String Column2 = (String)row.getAttribute("Column2");

String Column3 = pageContext.getParameter("Column1");
String Column4 = pageContext.getParameter("Column2");

MessageToken[] tokens = { new MessageToken("COLUMN1", Column1),
new MessageToken("COLUMN2", Column2)};

OAException mainMessage = new OAException("FND",
"DELETE_RECORD_WARN", tokens);

OADialogPage dialogPage = new OADialogPage(OAException.WARNING,
mainMessage, null, "", "");

String yes = pageContext.getMessage("AK", "FWK_TBX_T_YES", null);
String no = pageContext.getMessage("AK", "FWK_TBX_T_NO", null);

dialogPage.setOkButtonItemName("DeleteYesButton");

dialogPage.setOkButtonToPost(true);
dialogPage.setNoButtonToPost(true);
dialogPage.setPostToCallingPage(true);

dialogPage.setOkButtonLabel(yes);
dialogPage.setNoButtonLabel(no);

java.util.Hashtable formParams = new java.util.Hashtable(1);
formParams.put("Column1", Column3);
formParams.put("Column2", Column4);
dialogPage.setFormParameters(formParams);

pageContext.redirectToDialogPage(dialogPage);
}

7. Add Delete Confirmation Handler Code to SearchCO.processFormRequest()

import java.io.Serializable;
import oracle.apps.fnd.framework.OAApplicationModule;
...

else if (pageContext.getParameter("DeleteYesButton") != null)
{
String Column1 = (String)row.getAttribute("Column1");
String Column2 = (String)row.getAttribute("Column2");
Serializable[] parameters = { Column1 };

OAApplicationModule am =
pageContext.getApplicationModule(webBean);

am.invokeMethod("deleteRecord", parameters);

OAException message = new OAException("FND",
"DELETE_CONFIRM", null,
OAException.CONFIRMATION, null);

pageContext.putDialogMessage(message);
}
