Print, Save form in PDF Format from SAP

Hi,

The business users would like the ability to save, print a form, i.e. a Contract (VA42/43) in a PDF format.  My understanding is, this feature/option is should be available through Goto menu through a feature/option PDF Displaywhich opens the form in a PDF Viewer that allows the user to Print and Save the form in a PDF Format. 

My question is what is required in SAP to make this feature/option available to an end user, is it a security role, a user parameter, a trigger of a function module...etc.....any help on this would be much appreciated

Thanks,

Sean
