How to directly launch a form function via URL

Hi,
I'm looking for a possibility to directly launch a form function that finds and diplays a reuqested organization item. I have a couple of questions for that:

• First of all I would need a method for finding out the appropriate form function name for the one that is executed when pressing Ctrl + F11 on the "Organization Item" form. I found the "Execute Query" (FND_FNDCPMPE) form function, but I'm not quite sure if this is the one I'm looking for, as it looks like this is not valid for "Manufacturing Manager" responsibility. But pressing Ctrl + F11 on the "Organization Item" form with "Manufacturing Manager" responsibility is allowed...
