Not able to access Enterprise Workspace through API call

HiAt the moment I'm trying to get familiar with LAPI. One of the first things I'm working on is to access the Enterprise Workspace via LAPI according to the example written in the builder help environment of ll 815. But this doesn't work as I expected. Although the AllocSession function return a correct value, the following call to the AccessEnterpriseWS fails. I'm building the session object with the Admin account.Does somebody know what's going on or did somebody succesfully use accessEnterpriseWS function as described in the examplecodeThanksLudwig Stokkelaar
