Click Add.
A new screen displays.

Type a name for the expression. The name must not exceed
100 bytes in length and cannot contain the
following characters:
-
> < * ^ | & ? \ /
-
- Type a description that does not exceed 256 bytes in length.
-
Type the displayed 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.
-
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
-
-
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.
-
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.
