Selective Access to Oracle E-Business Suite

Hi All,

We will be maintaining some data setups in our Oracle HRMS module for Cost Center Alignment,

and we would like to temporarily restrict business users from accessing besides the HRIS Team and IT Support.

I know there is like a "backdoor" access in Oracle EBS wherein we can use an alternate URL instead of using the normal URL in ICX_PARAMETERS but where can i find it?

any thoughts?

Thank you.
