Is it possible to send file as a attachment to internal Peoplesoft / 3rd party using integration bro

Hi,

I came across this SR: https://support.oracle.com/epmos/faces/SearchDocDisplay?_adf.ctrl-state=wmmmil0m1_58&_afrLoop=519134935419568

It tells user is able to send small files and solution has been provided to send large files through IB.

I am trying to send a file attachment using the below logic to internal node : PSFT_EP

++++++++++++++++++++++++++Code used+++++++++++++++++++++++++++++++++

import PS_PT:Integration:IRequestHandler;

class I_TEST_IB_APP_CLS implements PS_PT:Integration:IRequestHandler

   method OnRequest(&requestMessage As Message) Returns Message;

   method OnError(&requestMessage As Message) Returns string;

   method errorhandler(&oSession As ApiObject, &fileLog As File) Returns string;

end-class;

method OnRequest
