The Random Substitution masking format uses the specified substitution column
as the source of masked values. The values in the substitution column are randomly
ordered before mapping them to the original column values. As a masking operation
renames tables temporarily, the substitution column must be in a table that has
no masking column. Also, you may want to ensure that the substitution column has
sufficient values to uniquely mask the target column.
Unlike Deterministic Substitution, Random Substitution doesn't do deterministic
masking, and thus, doesn't require a seed value. To learn more, check Random
Substitution in the Data Safe documentation.
