Question:
Can Boolean fields, like 'has_CI', be used within Dependent Attribute Controls?
Environment:
CA Service Desk Manager 14.1 and 17.x
All Supported Operating Systems
Answer:
Boolean fields have only two possible values, usually "true" and "false", with no blank values.  Boolean fields ALWAYS have a value filled in (i.e. True or False).
The Dependent Attribute Control is designed to check if the field is filled in/has a value and not if the value is true or false. 

Therefore, the use of Boolean fields, like has_CI, will not work with Dependent Attribute Controls since there is always a value present in these types of fields.
