Business partner address data in smartforms

Hi all,

I am just creating a new smartform in SAP FSM and want to integrate address data of the buisness partner, so that the fields are prepopulated automatically. I have found many default fields inside in the property selction screen, like city and country, however i am missing:

• Street
• Street number

I have tried :

@ref(businessPartner.street)
@ref(businessPartner.streetNo)

but they're not working. How can i define these fields? Any other suggestion?

Thanks in advance!
