1.3.4.8.7 Comparison: Equal or One/Both Fields Null (Solutions)
The Equal or one/both field null (Solutions) comparison determines if both attributes are equal, or either attribute is null.
Use the Equal or one/both field null (Solutions) comparison as a way to apply a Match rule only to a subset of the data when certain attributes are equal or data is missing.
The following table describes the configuration options:
| Option | Type | Description | Default Value |
