FNR
The FNR generator transforms Norwegian national identity numbers. In Norwegian, the term for national identity number abbreviates to FNR.
The first six digits of an FNR reflects the person's birthdate. You can choose to preserve the birthdates from the source values in the destination values. If you do not preserve the source values, the destination values are still within the same date range as the source values.
Another digit in an FNR indicates whether the person is male or female. You can specify whether to preserve in the generated value the gender indicated in the source value.
The last digits in an FNR are a checksum value. The last digits in the destination value are not a checksum - the values are random.

How to configure
To configure the generator:
To preserve the gender from the source value in the destination value, toggle Preserve Gender to the on position.
To preserve the birthdate from the source value in the destination value, toggle Preserve Birthdate to the on position.
Toggle the Consistency setting to indicate whether to make the generator consistent. By default, consistency is disabled.
If you enable consistency, then by default the generator is self-consistent. To make the generator consistent with another column, from the Consistent to dropdown list, select the column. When a generator is self-consistent, then a given value in the source database is always mapped to the same value in the destination database. When a generator is consistent with another column, then a given value for that other column in the source database results in the same value in the destination database. For example, if the FNR column is consistent with a Name column, then every instance of John Smith in the source database results in the same FNR in the destination database.
If Structural data encryption is enabled, then to use it for this column, toggle Use data encryption process to the on position.
