in a sales order we have different representatives (partner function "VE") on item level due to commission issues. Now we have the requirement to prevent the invoice split with different representatves on item in order-related billing. While in copy control it is easy to prevent invoice split due to different VBRK-fields we have not found a userexit ( or copy-control) to prevent invoice split with different partners.
Anybody has an idea to this issue?
Thanks for your help.
