Hello Expert,
Can anyone please tell me, how i can change a reference field(XBLNR) for billing document in VF03 by using function module or using BAPI. I am creating billing invoices with help of 'BAPI_BILLINGDOC_CREATEFROMDATA' reference field is populating with Invoice billing number. But i want to update this reference field with other number than billing number.
Thank you in advance.
