ME23N - Enable Printing

Hi all,

Here is what I notice in the system:

When you create a PO and try to view it in me23n the button Print Preview is enabled and I can see all the messages

and print it without having to save it first in me22n.

How is this possible?

Because in a different SAP system I am trying with the same message type and SmartForm but there I have to save it first in Me22n and then I have the message type in me23n.

Is there any workaround that has been done during installation and customization?

Thanks in advance,

Ilina
