SQL table to query the HCM staging area identity store

Hi

I'm pretty new to IDM and need help please.

I'm trying to locate which table view in SQL would give me the manager details brought from HCM into the HCM staging area identity store.

I was advised that this information would be in the SAP_MASTER IS but I'm confused as I only have 2 IDs - one productive & the other the HCM staging area

Please could you give me some info on this.

IDM 7.2 SP9

Database - SQL

Thanks
