Description
When calling data from the InputDescriptor, which contains data with more than 5,000 variables, the custom SVB node will trigger mapped subset, which maps variable selections into a smaller number of variables for those analytics that have maximum number of variables set to 5000. And running such a SVB node will result in the following error message:
Cause: When a node creates on output (for subsequent analysis) an InputDescriptor with a mapped data source, then only those variables that were included in the map are available to the interactive user interface. However, when reviewing the input data file (document), the complete (original) data file will be left intact.

If DataIn(1).IsMappedSubset Then DataIn(1).Unmap
