The SIDE is required.
It would help if there was a sample reference dataset or at least some documentation of the allowable flags for these codes. I doubt if it will appear, so us users will just have to reverse engineer the options and document them here and on Stack Exchange. The SIDE field is REQUIRED in the locator builder, so something has to be populated. They are not intuitive. I had a fruitless search in the help for a list of codes. I then searched the configuration file and can guess that Parity can be L, R, M for perhaps Left, Right, Mixed. So what would SIDE use? Maybe the same but a D(ual) might be an option. Perhaps BLANK is allowed, but never NULLS I suppose that is because someone might be using a shapefile still where nulls are not supported. The default output of a locator is still set to shapefile.
