Hi Shane,
There are no fixed values or places where you set what value is being passed into this prop. It is up to you to decide and code what values you want to send to this variable. Do remember that prop60 is a traffic variable and you should and should contain relevant info only.
The second question in your query " how to get my information to send to the right reporting suite " is a bit ambiguous. It again depends on you as to which report suite you want it to be passed to. If you're looking to check whether data is being passed to the correct report suite please go through this document.
Please let us know in case you have any more queries.
Thanks
Nikhil
