Process On Value Request: Read value from other screen field

Hello,

on a screen, I have to provide an F4-Help for the possible payers available for a certain customer. The customer number can be set in another field of the same screen (zkb_0200-kunre from DataDictionary).

In PROCESS ON VALUE REQUEST I have:

FIELD zkb_0200-kunrg MODULE f4_kunrg.

In the Module f4_kunrg I try to access the number of the selected customer by accessing zkb_0200-kunre. But the variable does not hold the value shown on the screen, instead it is empty.

In the Module f4_kunrg I have:

PERFORM select_regulierer USING zkb_0200-kunre.

How can I access the KUNRE information shown on the screen in order to select the right payers for the selected customer?

Thanks a lot. Obviously, points will be rewareded.
