Hello,
The Note 189618 explains how the tray selection is set for Smartforms.
For each page of the form, the paper resource can be specified within
the form from transaction smartforms.
eg: /nsmartforms -> <Form Name> -> Change -> FIRST First Page
-> Resource Name -> eg: 'TRY02'
If all of above are correct, you may also check the device type used and see if it contains
the correct command in 'Print controls' for TRY01, TRY02, TRY03 etc.
Regards,
Wen Peng
