Check HCM module wise objects and reports

Dear Gurus,

Do you have any idea how to check HCM module-wise objects and reports?

For example, below are reports can be checked via SE38,

RPL* Lists

RPS* Statistics

RPC* Payroll reports

RPU* Utility reports

RPT* Time management reports

RPAPL* Applicant data reports

RPI* Reports for creating batch input sessions

RH* Reports for personnel planning

however, if we don't know their meanings, by which t-code can we have a hierarchy list like:

Reports for personnel planning  - RHINTEN10

                                                 RHINTEN20

                                                 RHINTEN30

Time Management Reports - RPTxxxx1

                                          RPTxxxx2 etc.

Thank you for your kindly advice.

BR,

Alina
