Diagnosis
You have selected an incorrect invoice type for the given accountingdocument.
The problem can appear if:

• You made a correction in a condition, generated an accounting document
to it, and you have set the value R (reversal invoice) in theCorrection/Reversal Invoice Identifier field in the CreateCorrection/Reversal Invoices report to create an invoice.
If you have already created a reversal invoice, you will not be able tocreate a correction invoice for the same condition.

• You created an accounting document during a reversal run, and you have
set the value C (correction invoice) in the Correction/ReversalInvoice Identifier field in the Create Correction/ReversalInvoices report to create an invoice.

System Response
The system does not allow you to save your changes.

Procedure
You can make one of the following:


• Change the Correction/Reversal Invoice Identifier in the
indicated line.

• If you wanted to make a reversal, you need to reverse the already posted
changes to the condition, and reverse the previous changes instead ofsetting the relevant condition to 0.

• If you wanted to make a correction, instead of reversing the posting,
change the conditions in the real estate contract and post them with theperiodic posting transaction.
