1. Adjustment Reversal of Billing Documents
Though this post is coming after the post of ISU ASSESS workflow, it was not intended too (almost a year
now ). Link is here.
As ISU ASSESS uses Adjustment reversal functionality to reverse the Billing documents which are already
invoiced. So an understanding of this process is necessary to fully understand that process or I should say
the workflow.
So without any delay the standard SAP text can be found here, below is the copy of it with some
screenshots for some fruitful understanding (fingers crossed ,just been hopeful that I am able to
communicate the functionality clearly. :P )
So we can reverse a billing document for adjustment when the billing document has already been
invoiced. The customer may have already received the bill and so probably we do not want to reverse the
print document and all the billing documents. In this case, re-billing produces a difference document.
This ensures that the customer only sees the difference as an adjustment of the previous bill.
Example: Adjustment Reversal Process in Detail
An B1 billing document for electricity, has been invoiced with the print document number P1. Adjustment
reversal consists of the following steps:
1. Reverse billing document B1
Adjustment reversal allows us to just reverse the billing document B1 without having to reverse the
corresponding print document P1.

2. Multiple Billing Docs Single Invoice
This is an advantage, for example, if print document P1 also contains the billing documents B1, B2 and B3.
We reverse the incorrect B1 document without having to reverse the whole P1 print document and the
billing documents B2 and B3.
Selection of Billing Doc for Adjustment Reversal
Success message
The billing period for billing document B1 is opened again and a billing order is created.

3. Single Billing Doc left
The billing document B1, which has now been reversed for adjustment, is entered in this billing order.
2. Making billing-related corrections
We make all the necessary corrections, such as meter reading corrections or changes to installation facts.
Change in the meter reading
3. Rebilling B4 (with invoicing)
When this billing order is rebilled, the document line items of document B1 are inverted to negative line
items and attached to the new billing document B4. This produces a difference bill, which clears the errors
made in B1.

4. Difference Line Items shown
Only single adjustment reversal is permitted in the IS-U standard.
This means that document B4 from the example above cannot normally be reversed for adjustment again.
Reason: The connections between billing documents and print documents can be lost if billing documents
are reversed for adjustment several times. In addition to this, it does not generally make sense to create a
chain of difference bills.
If exceptional cases arise and we have to execute adjustment reversal more than once, we can use the
enhancement EBIA0029 Permit Multiple Adjustment Reversal to activate this feature either
generally or just for certain situations.
Post on Budget Billing coming soon. :)
