Workspace in Webclient UI

Hello experts,

I am configuring transaction launchers (into R/3 and CRM). Getting to R/3 and creating hyperlinks to the internet is straightforward, but I am missing the workspace method for navigation into CRM.

Does anyone know what CRM 2007 (or CRM 5.0/1/2 ) replaces the workspace method in old CIC with ?

Many thanks,

Francis
