unknown

Description

Create a condition for when a certain piece of information is unknown.

Example

If you want to trigger a warning when a person's domicile has not yet been registered in the case, attach this condition to the warning:

p is Person
p.is_pep is unknown

is unknown never asks for the information

is unknown never makes the information it checks necessary, even with "Create missing values" set to yes. So this rule never asks for duplicate_found:

p is Person
p.email is known
and then
p.duplicate_found is unknown

is known does make its information necessary. To have the value asked for and still react to it being missing, negate it instead:

not (p.duplicate_found is known)

Condition	Asks for the information
p.first_name is unknown	no
not (p.first_name is known)	yes
p.first_name is known	yes
SNEAKY(p.first_name is known)	no
