Custom Report Development

Dear Experts,

       Our client wants to create a SLA report for which they need the below information about the Access Requests Raised.

1. Request Type
2. Request date
3. Priority
4. Requestor details
5. Date of Request approved by all levels
6. Rejected date and level of rejection
7. Request status
8. Comment in each level

Basically, I would like to know which GRC Tables will give me the above information. Any help is really appreciated
