Scripted calculation view returns no datasets

Dear community,

I have a scripted calculation view which does not return any dataset. I am sure that the logic is correct, because when debugging the underlying stored procedure (to be found in _SYS_BIC.packagehierarchy/viewname) the variable var_out contains all expected datasets.

I have checked that the columns in var_out at debug time correspond to the output columns of the calc view.

Is there anybody who encountered the same issue?

Thanks in advance.

Marco
