The Raiser's Edge NXT Web View Gift List filters on Gift constituency code, not constituency code.

If constituency codes are present on a constituent (on the Bio2 or Org2 tab in Database View), then Gift constituency code defaults to the primary constituency code, or the first one that is "in date" based on the Gift Date if constituency code Date From/Date To values are present. The Giff constituency code can be edited on the gift record or in Batch during gift entry if a value other than the default is desired.
