Invoice List SAP script - Problem with SAP script functionality

Question

Hello Friends,
I am working on SAP script - Invoice List SD_INVOICE_LIST. The invoice list contains the underlying billing documents. As per the standard functionality, in the line items, its printing the underlying billing documents with the net value. My requirement is to dig these line items into another level, meaning, I need to display the line items of billing documents  as well(like material, material description, quantity, net price and net value of that item etc).
The billing linte item informatin is stored in VBRP table and the VBRP structure is not at all defined in the print program of SD_INVOICE_LIST (I.E.RVADIL01). Change of standard SAP program is not an option for me here.
In the external subroutine we can fetch these line items for each billing document in the invoice list. However, my question here is how to take these line items back to the sap script and print them in SAP script (We can print one line item but how to loop these fetched lines and print them on SAP script. Any help in this regard would be greatly appreciated.
I think there is no standard smart form exist for the invoice list. Please also let me know if there is any standard smart form available for INVOICE List.
Thanks in advanace for any help in this regard.
Best regards,
Siva

Hi
As you cannot change the standard, you will have to see if there are any enhancements provided in the print program. if not you have to copy into a custom one and do changes accordingly.
