Configuring a Customized Expression

Procedure

1. Go to Policies → Policy Objects → Data Identifiers.
2. Click the Expressions tab.
3. Do one of the following:
   • Click Add to create a new entry.
   • Click an entry to change the settings.
4. Type a name. The name must not exceed 256 characters in length and cannot contain a vertical bar (|).
5. Type a description that does not exceed 512 characters.
6. Type the display data format.
7. Type an example for the display data.
   For example, if you are creating an expression for ID numbers, type a sample ID number. This data is used for reference purposes only and will not appear elsewhere in the product.
8. Choose one of the following criteria and configure additional settings for the chosen criteria (see Criteria for Customized Expressions):
   • None
   • Specific characters
   • Suffix
   • Single-character separator
9. Test the expression against an actual data.
   For example, if the expression is for a national ID, type a valid ID number in the Test data text box, click Test, and then check the result.
10. Click Save if you are satisfied with the result.

    Note Save the settings only if the testing was successful. An expression that cannot detect any data wastes system resources and may impact performance.
