SAP T-Codes with Functiona Area, Business Process, Sub-Process wise details

Hi Experts,

I am Involved in GRC AC5.3 implementation Project. In this we need to work on complete Role-Redesign Process, which involves building of New Roles as per their requirement (Transaction used in past one Year). We find 3500 T-Codes, which are used by the client from past one year. We need to segregate the All the T-Codes into Functiona Area, Business Process, Sub-Process wise.

*Is there any data source available on Complete information on SAP T-Codes with Functiona Area, Business Process, and Sub-Process wise details.

Thank and Regards,

Sathish...
