Hi Martin
If the Header data for billing are different, then you can not combine the deliveries into one Billing document.
For example, you can not have two different Payer or two different Payment Terms in one Billing document. 
Therfore,if the
PAYER,PAYMENT TERM, BILLING DATE,  DESTINATION COUNTRY AND INCOTERM are different then you can not combine them in one Billing document, whatever settings you may do .
In standard settings ,if the above criterias are same, then system always tries to combine the deliveries into one Billing document (provided you have not set any item dependent Invoice split).
Ensure in the copy control VTFL, at Item level, Copying requirement should be "004" and in the VBRK/VBRP field value should be "001"
at Header level,Copying requirement should be "003".
If you have not used any user exits or have not made any Item dependent Invoice split etc, then this above settings must meet your requirement.
In your case just check, whether the criterias for combining the deliveries are same or different for both the deliveries.
