Hi @mohamedouat 

Service offerings are related to users as subscribers. I believe that if you relate your catalog item to a service offering, users whose requests complete are added as subscribers to that offering. You may have to add the necessary related lists to see the data.

The other data doesn’t seem to be directly related to the offering itself but more to the requested item attributes. Typically these form part of a request to enable it to be fulfilled. What do you need this data for? This will help you decide where to store it.

I hope this helps!
