ATrouble in passing parameter to PO Form from a Custom OAF Page

Question

Hi All,
I have created a custom OAF page from where I am calling the standard purchase order screen, the URL which i am using is as below;
form:Respapplshortname:Respkey:STANDARD:PO_POXPOEPO:po_header_id={@PoHeaderId}
I have done the below Form Personalization for the same
Create a when-new-form-instance personalization and create following actions
1)
Type: Builtin
Builtin Type: DO_KEY
Argument: ENTER_QUERY
Create a WHEN NEW ITEM INSTANCE personalisation and create the following actions
1)
Type: Builtin
Builtin Type: GO_ITEM
Argument: PO_HEADERS.SEGMENT1
2)
Type: Property
Object Type: Item
Target Object: PO_HEADERS.SEGMENT1
Property Name: VALUE
Value :==:'PO_HEADER_ID'
3)
Type: Builtin
Builtin Type: DO_KEY
Argument: EXECUTE_QUERY
Here in the below mentioned step
Type: Property
Object Type: Item
Target Object: PO_HEADERS.SEGMENT1
Property Name: VALUE
Value =:253253
If I hard code the value 253253(which is the header_id for PO_NUMBER 10031791) in the field 'value' then the PO_NUMBER form works as expected(PO Form opens up in queried mode and all the data of the PO_NUMBER is pre-populated)
My query here is how do I pass a parameter from OAF page to PO_NUMBER form so that we are able to pass the value dynamically instead of hard coding the value(253253 as mentioned above).
Please revert back as soon as possible in case anyone has inputs or better ways of achieving the above problem statement

Did you ever figure out how to resolve this issue. We are facing the same issue and developer is not able to figure out.
Thanks.
