ESS User maintenance by T-code HRUSER

Hi,

I have been creating ESS users ( P Users ) by T-code HRUSER. For instance, there is an employee number 5. It does two steps for us.

1. Creates R/3 user as P00000005.

2. Maintains system user name at IT 105 as P00000005.

But, now I need to change the user id format created by HRUSER. I need to create T users instead of P users. Eg. T000005 and change the number of digits too.

Please let me know how to achieve this.

Thanks.
