Who's Who customizing in ESS

Hi,

We are using portal 6.0 SP17, with ECC 5.0 and the Web Dynpro based ESS applications.

1)

Is it possible to customize the fields that are displayed in the standard application, without Java coding ?

If not, can someone give me a hint of how to do that. Is it required to use the JDI -environment, or is there a easier way to do it ?

Best Regards,

Kristian Rantakoski
