How To Fix AH787 - Doc.cálculo &1 anulación de ajuste ya anulado en facturación

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 787

• Message text: Doc.cálculo &1 anulación de ajuste ya anulado en facturación

¿Qué causa este problema?

In the billing order for installation &v2& (see the billing document
for scheduled billing date and billing transaction), billing document
&v1& is marked as having been reversed for adjustment in the
<LS>Doc.no. in adj. rev.</> field.
However, billing document &v1& was already reversed in invoicing; see
the offsetting document &v4& for invoicing document &v3& (entry in
table ERCHC with SPCANC = "X").
You should not process the billing order for which the adjustment
reversal is set; this would only generate a difference bill relative to
billing document number &v1&. This could mean that the customer is
charged too little since the invoicing document has been reversed (and
this counters the point of an adjustment reversal).

Check the billing and invoicing situation.

the billing order using Transaction EA24 <LS>Delete adjustment reversal
