RDI error: DIN A4 not supported

Hello Community,

I'm trying to connect my ERP to a OMS that need RDI files.

First, I created a new output device:

Devicetype: UCPLAIN

Device Class: Standard

Access Method

Host Spool Access Method: L

Command Set ID copy /Y &F \\XXXXXXXXXXXX\&f > NUL || ECHO "ERROR copying &F"

Then in transaction SE71, I set the smartform that I want to test, to RDI Output of type X.

But when I try to print, I got the error:

Device type UCPLAIN does not support page format DINA4

Best regards
