Best way to handle inbound interface postings

Hi all ,

We have an external interface from a legacy system , which posts to SAP . This interface creates the billing document in SAP and now we want to modify a field in the accounting document with the billing document reference number .

Can anyone suggest what would be the best way to handle this interface. Is this a purely ABAP development and what should be the inputs provided to them .

Thanks ,

    You have not provided clear requirements. I assume you have SD Billing Docment created by the interface and you want to copy the SD Billing Doc No in the reference field. If yes, you can take help from your SD Colleagues to have the XBLNR of Accounting document updated. If that does not help, why not keep the accounting document no range as external. Now for the SD Billing Doc and accounting doc keep the same no range and you will have the same doc no for Accounting and billing document

    Thanks & Regards
