Hi i am creating a customer using XD01, we can check the data in FD32 or KNKK table. The field KNKK-SBGRP should be filled with the first letter of the customer's name, if the first letter of the customer's name is a special character or it is a number (0 to 9), I know there is an exit for Xd01, SAPM02FD. i need to write the code can you please advise more???
