Two portals with single Backend system

Hi,

We are having ECC as backend and EP as frontend for HRMS(HCM) and will connect to that using URL (www.host/port/); similarly, can we create another URL through we can access other SAP modules like SD, MM, FI ?

So, 1^st URL will have login page and takes to ESS and MSS page (HCM)

And 2^nd URL will have login page and takes to other modules

I knew, we can handle this using role management such a way that who need to access ESS/MSS will have those roles and for other modules will have different roles; but our requirement is to have different login page for both.

Regards,
