Launching Oracle E-Business Suite Forms from OA Framework Pages

To launch an Oracle E-Business Suite form from OA Framework, you must first define a button, link or image web bean.

Declarative Implementation

Step 1: In the OA Extension Structure pane, select the region in which you want to create the web bean to launch an Oracle E-Business Suite form.
Choose New > Item from the context menu.

Step 2: Set the ID property for the item, in accordance with the OA Framework File Standards, and set the Item Style property to button, image, or link.

Step 3: Set the Destination URI property of the item with a value following this format .

Syntax:
form:responsibilityApplicationShortName:responsibilityKey:securityGroupKey:functionName

Step 4: If you wish to pass parameters to the form, set the Destination URI property with a value using the following format (Note that the parameter list is delimited by a space between each "parameter=value" pair):

Syntax with parameter:

form:responsibilityApplicationShortName:responsibilityKey:securityGroupKey:functionName:param1={@value1}

for Example:
Here I am Launching Invoice Workbench FORM. It's Query Invoice Workbench data on the basis of passed Parameter.

Item: MessageStyleText
ID:InvoiceId

Destination URI ="form:SQLAP:PAYABLES_MANAGER:STANDARD:AP_APXINWKB:INVOICE_ID={@InvoiceId}"
