Ignore Constant

Ignore is a constant that can be used in expressions to state that the mapping must be ignored. They are especially useful in conditional expressions. 

I.e. Do not change the target attribute when a specific condition is met.

Here are a few examples of Ignore being used: 

Ignore the mapping if the employee is terminated (this will not change the target attribute):

WHEN Employment.EmployeeStatusCode == 'T' 

WHEN Employment.EmployeeStatus == 'Terminated' 

THEN Ignore

This mapping will be ignored for all terminated employees

 

Ignore the mapping if this is an update

WHEN IsUpdate

THEN Ignore

This mapping will be ignored for all employees whose record has been updated

 

Ignore the mapping if the employee is located in New York City or Atlanta

WHEN Location.City.OneOf('New York City, Atlanta')

WHEN Person.AddressCity.OneOf('New York City, Atlanta')

THEN Ignore

This mapping will be ignored for all employees located in New York City or Atlanta
