Issue in fetching Historical Data in Org. model

Hi Experts,

We are having a requirement where we need to display the service team data related to employee.
Currently when Employee is moved from Level-1 to Level 2, and we run the report but we are getting the service team which is associated to employee today not at the time when interaction record was created.

We searched the tables HRP1000, HRP1001 but it did not work. Can anyone give some idea where this historical data of Organizational data stored related to service team.

Any inputs will be appreciated.

Thanks!

Regards,
