To answer your question...there is a function module SAPGUI_SET_FUNCTIONCODE...which can be used to trigger a event on the screen from the PBO to goto PAI without the user doing anything...
As soon as the function module is executed the PAI is triggered...
However, i am not aware of something like this to happen when a user enters some data on the screen..
If u want to execute the session manually U can do so by using sm35.
But if U want the session to be processed without going to SM35 then use SUBMIT RSBDCSUB with parameters in ur BDC program.
*******rewards some points.
