Billing Split Error

Dear All,

While creating collective billing doc (VF04) the system is given the reason for split is Different Ship to Party Region. My copy control requirement from Delivery to Billing is 003 (Header/dlv.-related).

Please guide me which requirement to be used or new requirement is developed.

Scenario is as follows,

1) Three Different sales order with different Ship to Party but same Sold to Party

2) Three Different Delivery Order with three different ship to party

3) Now I want to create only one billing document for these three deliveries as my Bill to Party and Payer

is same.

Thanks & regards,
