Billing Split Combination

Dear experts,

Please advise me on the following billing split requirement:

- Order related billing

- Multiple orders be invoiced by one invoice (standard split criteria)

- One order should be completely invoiced by the same invoice

- Invoice can only have maximum number of line items (defined in TVKO-MAXBI)

Routines 003/ 006 are checking on VGBEL but they don't allow multiple orders on one invoice.

Thanks

Martijn
