About billing split by quantity ,Source code

Hello all,

Does anyone know if its possible to split the billing document by quantity on the item.

I was only able to find split by items but nothing related to quantity.

If it is available , i want to see the Source code

In copy control VTFL you need to maintain the field named VBRK-VBRP as "XXX" (invoice split) at item level.

Thank you in advance.

[For example Source]

DATA: BEGIN OF ZUK,

MODUL(3) VALUE '001',

VTWEG LIKE VBAK-VTWEG,

SPART LIKE VBAK-SPART,

ABTNR LIKE LIPS-ABTNR,

EMPST LIKE LIPS-EMPST,

END OF ZUK.

ZUK-SPART = VBAK-SPART.

ZUK-VTWEG = VBAK-VTWEG.

ZUK-ABTNR = LIPS-ABTNR.

ZUK-EMPST = LIPS-EMPST.

VBRK-ZUKRI = ZUK.

ENDFORM.
