Have a look at DEMO_DYNPRO_F4_HELP_MODULE - the trick I think you are looking for is to use function DYNP_VALUES_READ to get the value of one field when F4 is selected on a second field. The DYNP_VALUES_READ will read what is on the screen even if the user hasn't pressed enter i.e. if the user has just keyed "123" into storage location and tabbed to material and hit F4. The demo program explains this process using context sensitive list of flights for an airline.
