Submitting a concurrent Request by using Form Personalization. How to capture the Request ID as a Gl

Hi,

Basic requirement is to print Invoice Report from AR Transaction Screen. I have created special Menu under 'Actions' menu and launching the custom Invoice Report from DB Function (Execute Procedure option). Returning the Request ID to Form Personalization. I would like to capture this Request ID into a Global variable and want to display it to User. Please let me know how to assign a value to Global variable?

Thanks,
