Call a PAL function within a view in HANA?

Hi community!

Does anyone know how you can integrate the call of a PAL function (e.g tripple exponential smoothing) into a HANA view? I guess this must be achievable in a CE Script?

Business scenario: we would like to show a time series based prediction on a Design Studio dashboard. Because the datasource is near-realtime and rapidly changing, we would like to calculate the PAL function on applications request. how can this be achieved?

Furthermore I was not able to integrate ordinary db views in an analytical-view (it seems to only support tables? does anyone know the reason why?)

thanks a lot!
