If I understand you correctly, you want to automatically populate a DFF field?
Check to see if the View Objects offer access to that column, and if they do, access the VO in an Application Module and set the value there. If the VO does not offer access to that column, see if the Entity Object does and get access to the EO and try to set the values of the columns that way.
Thanks for your quick response. Your understanding is correct.
The View object offers access to that Attribute field, following is the VO and there is also an EO for that VO. How do i bring the custom field upto this VO. Do i need to create a new VO for custom SQL and then map that particular field to that attribute based on the requisition_line_id? Could please help me how to do the coding. can you please share if you have any sample code for it. I am quite novice to the OA Framework
oracle.apps.icx.por.req.server.PoReqDistributionsVO,oracle.apps.icx.por.schema.server.PoReqDistributionEO & RequisitionAM
First grab the value which you want to set in string variable.
String value = row.getAttribute("AttributeName");
Now just check what is the attribute name for the DFF Field. Suppose its Attribut2
then grab the DFF VO.
OAViewObject vo = (OAViewObject)pageContext.getApplicationModule(webBean).findViewObject("DFFVO");
Row row = (Row)vo.first();
Thanks Gaurav, this is really help ful. I want to extend the controller, please correct me if my approach is wrong.
If my approach is wrong please suggest what kind of extension i need to do.
Extending the controller and writing the logic in the process request
1) first getting the application module
2) getting the Cutom table field value from the SQL Query by creating a dynamic VO within the controller.
3) Finding the VO which has that DFF field.
4) get the result value from the dynamic VO from step 2
5) set value to the dff Attribute field for the current row.
Framework java coding is new to me. can you please provide the sample code so that i can mimic the approach. Any help will be greatly appreciated.
Thanks Aj. Finally i made some progress....but i am getting an error in the inst_top OPMN folder 10/10/08 15:37:14 Error: <connector name="OracleASjms" path="OracleASjms.rar" /> will not be bootstrapped since corresponding module declaration was not found in application.xml. I cleared the cache, bounced the webserver. Could not able to understand what is this error
Following is the code that i have written. I am not able to find out what is the error. please help me how to fix this error. there is no changes in the page and the value is not auto populating. the page is having the normal behaviour as the standard one.
Thanks in Advance for your help...

You are doing some things here that you should not be doing. First you should not be finding a view by a hard-coded name. You should be calling the getXxxVO of the AM. Second, you should really void calling prepared statements in OAF code. Third, you should be working with VOs only in the AM. Fourth, you should not be calling the getAttribute() on a row unless you have no choice for some reason. Use the VO row client interface and call getRequisitionId(), or use the RowImpl class of there is no client interface.
Here is what you can do to avoid these:
Create a custom AM. Personalize the page and add a stacked layout item. Make the AM of the stacked layout your custom AM, full path (not the Impl).
In your custom AM you will import the AMImpl of the AM of the page for which you are extending the controller. In your custom AM, you will create a public method to do your work. Create an interface class for your custom AM by going to the AM dialog->Client Methods and moving your method to the right.
Create a VO for the query of the prepared statement you had and add this to your custom AM. Use :1, :2, and :3 instead of ?. See the Java docs and dev guide to see how to execute your VO with the parameters.
In the method in the custom AM, call rootAMImpl = (rootAMImpl) this.getRootApplicationModule() to get the root AM of the page. Now you have access to the rootAM.getPoRequisitionLinesVO().
In the method in the custom AM, do this.getMyVO() and call executeQuery(), then use the getXxx() methods of the row class.
In your extended controller, do something like this:
OAStackLayoutBean stackBean= ( OAStackLayoutBean ) webBean.findChildRecursive( "IDOfPersonalizedStackLayout" );
ClientInterfaceForYourAM yourIntfForAM = ( ClientInterfaceForYourAM ) pageContext.getApplicationModule( stackBean);
If you follow the above, your error will likely go away, and you won't be breaking so many rules ;-)
Finally my issue is resolved by following the below approach. Thank you all for your support. I am closing the thread now.
1) created a message text input bean for DFF attribute10 field in the shopping cart page for requistion lines VO.
2) next extended the controller in the shopping cart page and wrote the defaulting value logic in PR for the above attribute field.
3) Enabled the descriptive flexfield for attribute10 in PO Req distributions. when we enable the DFF on the forms, a message text input will automatically create on the page (CheckOutDistPG).
4) Using por_custom_pkg defaulted the attribute10 value in PO Req distributions which was captured in the step1.
In standard plsql hook, I wrote the below logic por_custom_pkg.custom_default_req_dist
IF line_att10 IS NOT NULL
distribution_att10 :=line_att10 ;
-- distribution_att10 := NULL;
5) I have set the rendered property to false for attribute10 field in shopping cart page to hide (in my requirement i don't have to show on the requisition lines level).
6) Once we default the DFF attribut10 value in PO Req Distributions, the standard functionality will carry over this field to the PO Distributions. (Showing this Value in PO Distributions is my final destination)
