Connection between role, T-code and activity

Hi all,

I'm looking for am amswer how to find the connection between role, T-0code and activity, meaning that for exa. if in one role under S_Tcode there are few T-codes, and in all other objects in that role there are a lot of activities, how do I konw wich activity is related to each T-code?

Is there a table that contains this connection?

All the sdantard SAP tables such as AGR* or USR* have only part of the data and I need the whole connection, due to my client request to see a report for each user what is his SAP roles assigned, the T-codes and the activity for each and every one of them!

Thanks in advance.
