Assigning a Custom Masking Rule

Assigning a Custom Masking Rule

Mapplet rules can require values from multiple ports. You must map each source input column to a rule input and output port that you configure in the mapplet rule.
  1. In the
    Define | Data Masking
    view, click the
    Masking Rule
    column for the column that requires a mapplet rule.
  2. Select the mapplet rule from the list.
    The
    Custom Rule Assignment
    dialog box appears with the list of columns in the table.
  3. Select a source input column in the left panel and a rule input port in the right panel.
    When you select a source input column, the rule ports with same data type become available for mapping.
  4. Click the
    Link
    icon to create a mapping.
    An arrow appears that links the source port to the rule port.
    To create a mapping, you can also click
    Show Simple
    and map the ports.
  5. If you need to remove the link, select the source input port and the rule input port. Click the
    Unlink
    icon.
    The arrow between the ports disappears.
  6. After you map the rule input ports, click
    Next
    .
  7. Select a rule output port in the left panel and a source input column in the right panel.
  8. Click the
    Link
    icon to create a mapping. To remove a mapping, click the
    Unlink
    icon.
  9. Click
    Save
    .
    If the source database is Sybase and the target database is Hadoop, you must limit the custom rule assignment to a maximum of 20 columns. The workflow generation fails if you assign a custom rule to more than 20 columns.
