Search Help Exit - Very Urgent

Hello friends,

I have a search help which will take KAPPL and give me the results for KZNEP for the value of KAPPL.

I have created a search help exit for it. I am calling function module F4UT_PARAMETER_VALUE_GET, but i am not aware of what all parameters to be passed to this function.

Can anyone help me out in this. This really very urgent.

Thanks for all the help.

Regards,

Salil
