Customer Exit - CNEX0001

Hi Everybody,

I'm trying to implement function exit - EXIT_SAPLCJWB_001 of Customer Exit - CNEX0001 of PS module.

Here I'm trying to dynamically assign F4 help to User Fields PRPS-USR00, PRPS-USR01, PRPS-USR02 and PRPS-USR03.

I have tried using function module 'F4IF_FIELD_VALUE_REQUEST' to achieve this task. But I want to popup F4 based on user response. Say in some POV event. But how do we do that inside Function Exit????

Waiting for reponse....

Regards,

Deva.
