Extractor enhancement with user exit RSAP0001

[Former Member]

Hi Experts,

I need enhance a field "KLABC" from Table "KNVV" to Master Attr. "0CUSTOMER_ATTR", Ext.Structure "BIW_KNA1_S". I appended field "KLABC" in to KNVV.

Now I try to write abap code on include "XRSAU02". Could anybody help me to write code? i am not sure my code is true. Please consider KUNNR, VKORG, VTWEG, VKGRP, VKBUR.

Thanks Alot
