Hi Sridhar,
As Partha menstioned, ERP-Shop Floor Integration and Worker UI Management are OEE menus.
Also, the CTC creates 2 users: OEE_ADMIN and OEE_INTEGRATOR. Apart from these, no other technical users are required/created.
There is no user called OEESYS created by the CTC.
Best Regards,
Sulaksh
