If you get the error message ‘Invoice date after period’, you can solve this in the following way:

The reason for the error message: Invoice date and delivery date are in different periods.

Example: Invoice date in November, delivery date in October.

It is not possible to export the invoice with the period of the delivery date.

The invoice must be exported in the period of the invoice date. This can then be changed in DATEV Accounting while the documents are being posted. DATEV Accounting suggests posting in the period of the service date.
