SAP Error Message - Details

• Message type: E = Error

• Message class: AH - IS-U billing (master data)

• Message number: 779

• Message text: Doc. &1 (inv.doc. &2) del. from bill.order for inst. &3 sch. bill.date &4

What causes this issue?

Billing document number &v1& was reversed for adjustment; however, an
invoicing reversal was executed subsequently for its corresponding
invoicing document &v2&. In this case, the selection via this billing
document number can be deleted in the corresponding billing order.
For a non-reversed invoicing document, the selection generally
guarantees that the new billing of the billing order shows the billing
line items from &v1& as negative amounts, producing a difference bill.
