How can I copy the RITM number to another field such as short description or description to a sctask

[Cindyco]

I need to be able to copy the RITM number to a different field like short description, description or work notes to the sctask for all requests.  I am unsure of how this can be done.  It is a strange request because the RITM number is already available but we have ebonding set up to pull only certain fields from our sctask ticket to a custom application at a different company from our sctask ticket and they are only pulling certain fields.  

Any help would be appreciated.

We can store the value in some other field if you want to avoid the issue maybe worknote use the below code

current.work_notes=current.request_item.number;
