Microsoft has developed an E-Invoice DE extension.

This extension also allows you to export and send files in the ZUGFERD and XRechnung formats.

As a partner with customizations, we would like to adapt this slightly to include specific values and fields.

This is not possible because both formats are set to “internal” and are therefore not customizable.

We would like this to be changed so that we can use Evens to add additional XML strings and, if necessary, customize existing XML strings.

Otherwise, there is no way to make adjustments here.
