Functions in Data on Demand in Spotfire

Dear Community,

I'm loading my data on demand in Spotfire, using a 'data connection in library'. Everything works fine so far. But when I want to make custom expression (e.g. to use in my tooltip), a lot of functions are not available. When I import the dataset, these functions are available and it works fine. Does someone has any idea why this is? I prefer to load my data on-demand, but want to use these functions as well;)

Hope you are willing to help me.

Thanks in advance!
