Unique substitution

Unique substitution

Unique substitution masking ensures that each unique source value uses a unique dictionary value.
To mask a source value with a unique dictionary value, you can configure unique substitution masking. If a source value is masked with a specific dictionary value, then no other source value is masked with this dictionary value.
For example, the Name column in the source data contains multiple entries of
John
. If you configure repeatable masking, every entry of
John
takes the same dictionary value, such as
Xyza
. However, other source values might also be masked with the same dictionary value. A source entry
Jack
can also use the dictionary value
Xyza
. As a result, all entries of John and Jack use the same dictionary value. When you configure unique substitution masking, if all source values of
John
use the
Xyza
dictionary value, then no other source value uses the same dictionary value.
Unique substitution masking requires a storage connection for the storage tables. Storage tables contain the source to dictionary value mapping information required for unique substitution masking.
If the source data contains more unique values than the dictionary, the masking fails because there are not enough unique dictionary values to mask all the source data.
