Print Multiple GOS Attachments in WDA

Hello Experts,

I have below requirement in which I have to Print multiple GOS Attachments from HR Portal of My Trips and Expenses in Travel management.This is a pop window customised for Printing in the standard program for My Trips and Expenses in Travel management.

Below is the attached screen shot, Whenever user selects multiple attachments( GOS Attachments displayed in Pop Up using CL_FITV_GOS Class ) and clicks on Print Button, those attachments should get printed.

Kindly advise on printing multiple attachment contents in Web dynpro abap.

Thanks in Advance!
