Giving a Pop up for multiple selection after PAI

Example: If user wants to print a form from a standard tcode like Orders or Areements -- and based on the status of document he wants to print the document with or without Units on the form. He doesn't want to edit the Tcode to allow the option, instead he likes to get a pop up showing the options as soon as he selects the Print button.

Inside the smartform processing program: call the below FM to give the Pop Up and take the inputs to program based on that.
