Attachment in Manger's SAP inbox , Expense Report Workflow ,Travel management

  Dear Experts,

                         We are using custom workflow for Expense report process.

                         TRIP is raised in PR05 and goes for approval in SAP inbox and NWBC portal.

                        Now issue we are facing is that we when any attachment is uploaded,it can be seen in

                        NWBC screen by manager,but there is no attachment visible in SAP inbox decision step .

                        Also we are calling Secondary method of BOR in methods tab of Decision Task,this method

                        calls Next screen of PR05 in display mode.This is visible after approve via SAP inbox.

                        Here also we are not able to see attachment.

                       Kindly suggest how to get attachment in SAP inbox or in next screen after PR05 in display mode.

                       Any one out of 2 will work.Also there is no attachment visisble in workflow container so that

                       it can be binded to decision task

Thanks and Regards,

Aditya
