ORDERS05 Idoc: passing of customer group on sales order

Hi everyone,

I am trying to create a sales order in VA01 using the ORDERS05 Idoc. I need to populate the field KDGRP (customer group) in table VBKD.  This field is stored on the Sales tab on the header level of the sales order.

I am looking in the ORDERS05 documentation and I can't find a segment that would populate the KDGRP field in VBKD.

Any suggestions? I looked in the forums and OSS notes and found no information on this.

Do I need to modify the function module or create an extension to the IDoc to pass the value into KDGRP?

Thanks a lot!
