Invoice Splitting - for some shipping points and not others

Question

Dear Gurus, I have a requirement where for some shipping points I need to be able to split an invoice on sales order (i.e. a separate invoice for each customer order) and for other shipping points I require a single invoice for multiple customer sales orders.  Using the copy control rules for LF to F2, I have set the Refence Number to B but this does not achieve what I want.  Would it be possible to achieve this via a copy requirements routine and by setting the values in VBRK-ZUKI?  Do I just copy the standard 003 routine and apply my changes here?  If yes, where do I insert the code - the top or bottom?  Regards

In VOFM, first of all "Copying requirements" are used when we want to stop creating a target document from a source document or to prevent certain items from copying to target document under certain conditions. Copying requirements can't be used to do invoice split.
Data transfer routines are the ones that allow invoice split (in addition to allowing copying fields from source to target). Although "copying requirements" is a loosely used terminology, it is important we make distinction between copying requirements and data transfer routines as both are different and perform different functions.
SAP uses field VBRK-ZUKRI (a 40 character field) to store the combination of field values that are used as basis of invoice split. Invoice split happens if any of the fields stored in VBRK-ZUKRI differ across orders/deliveries (or their items) from which invoices are created.
We assign VBRK-ZUKRI during item copy control in data transfer routines. The fields are simply concatenated and assigned to VBRK-ZUKRI.
in VOFM, "Data transfer" routine 003 for Billing documents for example splits the invoice for each reference document, as shown by code below
Include FV60C003
*       For each reference document an invoice is created
FORM DATEN_KOPIEREN_003.
  DATA: BEGIN OF ZUK,
          MODUL(3) VALUE '003',
          VTWEG LIKE VBAK-VTWEG,
          SPART LIKE VBAK-SPART,
          VGBEL LIKE VBRP-VGBEL,
        END OF ZUK.
  ZUK-VTWEG = VBAK-VTWEG.
  ZUK-SPART = VBAK-SPART.
  IF KURGV-PERFK = SPACE.
    ZUK-VGBEL = VBRP-VGBEL.
  ENDIF.
  VBRK-ZUKRI = ZUK.
ENDFORM.
In the above coding we are concatenating VBAK-VTWEG (Distr channel), VBAK-SPART (Division), VBRP-VGBEL (Reference Order from billing item) as the criteria for invoice split. So if any of these field differ then it will cause a split. So basically we are creating one invoice for all items that reference a single order
So what you need to do for your requirement, is to copy the logic of data transfer routine 003 in VOFM to your own custom 9XX routine and make the assignment to ZUK / VBRK-ZUKRI only when shipping point (LIKP-VSTEL) is not equal to certain values that you don't want split to happen. It is better to maintain those shipping points in a custom table and make the check on the table rather than hard coding, so that in future it is easy to add more shipping points or remove existing ones if needed.
Also remember to assign the new data transfer routine number 9XX to all relevant item categories in VTFL for your target billing type and reference delivery type
