copy attachments from request to RITM

Hi,

I have a requirement to copy all the attachments from Request to the corresponding RITMs.

I have written an After-Insert Business rule on the Request table to achieve the same. But it seems the code is not working as expected.

Name: Copy Attachments to RITM

Table: Request (sc_request)

When to run: After - Insert

Script:

(function executeRule(current, previous /*null when async*/) {
   // Add your code here
   var ritm = new GlideRecord('sc_req_item');
   ritm.addQuery('request', current.sys_id);
   ritm.query();
   while(ritm.next())
   {
   GlideSysAttachment.copy('sc_request', current.sys_id, 'sc_req_item', ritm.sys_id);
   }
})(current, previous);

Any lead will be appreciated. Thanks in advance!!
