How To Fix EB323 - Reversal category of specially reversed docs not unique (tax adjustment)

EB323 - Overview

• Message type: E = Error

• Message class: EB - IS-U invoicing

• Message number: 323

• Message text: Reversal category of specially reversed docs not unique (tax adjustment)

What causes this issue?

The reversal category of the adjustment reversal billing documents is
not unique. The system executes invoicing again after an adjustment
reversal, whereby tax adjustment (non-reversal of tax amounts) is
necessary because the corresponding bill has exceeded a certain age, and
the adjustment reversal has a reversal reason from category 05 (reversal
due to customer fault) or 06 (reversal due to company fault). This
original print document &v1& contains multiple billing documents, not
all of which have undergone adjustment reversal with a reversal reason
from the same category. However, this is necessary because tax
adjustment is different for different reversal reasons.

System Response

The system cannot reinvoice the adjustment reversal billing documents.

How to fix this error?

Make sure that all billing documents of the original print document &v1&
have a reversal reason from the same reversal category for adjustment
reversal.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
