Definition: 

The situation, given specific values of other fields, when only one value of a field will cause the record to satisfy all of the edits. For instance, it might occur when the items that are supposed to add to a total do not add to the total. If only one item in the sum is imputed, then its value is uniquely determined by the values of the other items. This may be the first situation that is considered in the automated editing and imputation of survey data.

Example: The missing sum at the bottom of a column of numbers
