Mapping data between datasets

[sjabbour]

I'm having an issue mapping data between institutions when one dataset has a subset of variables in the second dataset. I run the first dataset through FIDDLE I get a set of discretization bins that I want to apply tot the second dataset. However, since the second dataset has variables that are not available in the first dataset, FIDDLE doesn't have any discretization bins to apply to those variables. Is it possible to have FIDDLE drop any data that it doesn't have any discretization bins for?
