I’m new to the product and just started working Exalate add-on.  My basic use case is that I would like to take a subset of bugs in one project and have them ported/ synched over to another project of the same instance (one way).  I believe I have my connection working but I'm getting error on affectedVersion requires synch.  I don't see versions listed in the available field mapping.  I did find an article on scripting (https://docs.idalko.com/exalate/display/ED/How+to+synchronize+versions) to synch a version but I don't see where exactly to add this scripting.  Can you point me to where exactly it is the groovy scripts are added on outgoing and incoming synch?  

Thanks.
