consolidated invoice for different divisions but one customer

Dear Experts,

I have a client requirement that in 'DBM collective billing' a single invoice is to be raised for a customer for orders created under different divisions.

I have checked the note 1010372 stating "Within the SD billing, you can use different criteria (for example, material group) to force a billing split. These functions are not supported in DBM."

In SD we can also use the copy routines to consolidate bills by influencing the split criteria updated in field VBRK-ZUKRI.

Please share if someone has worked on consolidating the bills for orders belonging to different divisions for one customer using the development in DBM.

Thanks,

DRB
