Description
You can use this function to cancel a reversal adjustment.
Prerequisite
You can only cancel an adjustment reversal for a billing document ifyou have previously executed an invoicing and a billing reversalfor the new billing. This means that another billing order has beengenerated that contains the billing document number in the Doc.no.in adj.rev. field.

What_to_do
In invoicing, reverse the invoicing document to which the billingdocument corresponds.
Delete the document number of the adjustment reversal from the billingorder.
This enables the new billing to generate a normal bill and not adifference bill.
You can now execute invoicing again, which produces an invoicingdocument that represents the orginal invoicing document.

Further_hints
You can also cancel an adjustment reversal as follows:
RESET N1
Reprocess the billing order that is marked with the billing documentnumber from the adjustment reversal.
A zero bill is generated as the difference bill.
Outsort the zero bill.
