How to extract user list and assigned systems in SAP IDM

I've connected around 10 abap systems to IDM, where different set of users already present in ABAP systems. After initial job the users got synced with IDM. Now I want to know totally how many users present in IDM and respective assigned systems. Also I've created few users from IDM. I want to know when the user created (historic data ). I use SAP IDM 8.0
