Enhancement - J1IIN - J_1I7_USEREXIT_J1IEX_CHANGE

Hi,

I wanted to implement the user exit J_1I7_USEREXIT_J1IEX_CHANGE for Excise Transaction J1IIN. Could any one advise how to do implement. Is it a BTE or any configuration needs to be made available.

I found out its a function module, but can't find in SMOD. I am stuck not knowing how to implement it. Please help.

Regards,
