Masking substitutes a dummy value for real, sensitive, data.
In the Column Mapping pane, click Cascade Masking.
The Cascade Blinded Columns window displays all blinded source columns, the target column they are mapped to, and the type of blinding.
If a source column has cell-level masking, the target column will have column-level masking until you specify masking criteria in the Clinical Data Models page.
Accept the cascade operation. Either:
Select a target table and click Accept.
Check Select All at the top of the window and click Accept.
