SAPScript and dynamic tray selection

Hi,

A customer of mine has 2 identical SAPScript layout sets defined with 1 minor difference - within the page attributes a different printer tray has been defined (attribute called resource name) in order to choose a different printer tray ...

I was wondering wether this value could not be dynamically set by the SAPScript output program (when opening the layout set or using a specific command) ?

I didn't really find any special function or parameter in the open_form function module ... I find it a shame that only for the tray functionality we have to maintain 2 layout sets ...

Or can this be achieved in a total different way?

Thanks,

Steven
