Numeric Key Masking Parameters

Numeric Key Masking Parameters

You can configure key masking for numeric values and generate deterministic output.
When you configure a column for numeric key masking, you can select a seed value for the column. When the PowerCenter Integration Service masks the source data, it applies a masking algorithm that requires the seed.
You can change the seed value for a column to produce repeatable results if the same source value occurs in a different column. Configure repeatable results when you want to maintain a primary key-foreign key relationship between two tables. In each rule, enter the same seed value for the primary-key column as the seed value for the foreign-key column. The PowerCenter Integration Service produces deterministic results for the same numeric values. The referential integrity is maintained between the tables.
