Hello Robert,
I dont think it is possible to set 2 output channels: print + mail at the same time on invoice.
There are several ways to setup the output channel:
- account master data -> collaboration,
- individual invoice - > edit output settings
- Application and user Management -> Output Channel Selection
You can set the output channel, but only one channel can be selected. It seems a specific requirement that is not fulfilled in the current releases.
Thanks,
Adie
