Xcelsius2800 refeshing data without webservie (excel Data?)

Hallo,

Id did some development on Xcelsius months ago and just started to aktualise my knowlage with Xcelsus 2008

I remenber refreshing dada from external excel-files while selecting spezial Regions so did'nt have to import whole model

but have a datatable(range) beeing refreshed ...

I have not found this feature ...what is the reason... how to do... maybe a connection to excel with Life-Office-Data...?

Thanks for any hints
