Calling Forms & Parameters

Hello,

I am calling an Oracle Form from OAF page using the following code snippet

               String destination =                     "form:INV:INVENTORY:STANDARD:INV_INVTVTUS:FIND:ITEM_NAME=" +                     itemName;

I am trying to pass inventory item id to the form so that inventory item will have the value populated rather than use typing the inventory item.

The form is getting opened however, the parameter is not getting populated.

How can I validate the form accepts parameters?

If the form doesn't accept parameters, how to create a function with a parameter so that I can populate the value in the form?

Appreciate any insight.
