Creating New users for SAP KM portal

Hello Experts,

We have developed one SAP KM Connector in JAVA environment. we need to test the same in SAP Environment and testing has to be done on multiple users (Approximate about 30k users).

And we don't want to create these users manually. Is there any quick way to create these many users? Is there any script that can be run so that 30k users are created on the sap km portal?

Any reference point related to this will be greatly appreciated.

Thanks in Advance,

Prashant.
