Prefill print form


Need help on filling printing form fields on form load.
So I have created custom data definition from baq and added criteria fields. Now I need to call this form from customer shipment entry on button press and prefill/pass params on form load. I can call this form from menu, but I have no idea how to pass data in RptCriteriaPrompt fields. When you call standart form, you can use ValueIn, but how to deal with this one?
