A rule is
available if the value of the pyRuleAvailable
property is set to Yes or Final (and is not
blocked; see below). Developers determine this value as they create or
save a rule.
A green icon at the upper right of the rule form indicates the current
setting. When presented in reports, the icon is brown.
Five availability settings
This property may have any of five values:
Yes
|
A circle and dot indicates that this rule is available. Rules
with a Yes value are visible to rule resolution
processing and can be executed.
|
No/Draft Mode
|
An empty circle indicates a rule that is not
available. Set the Availability of a rule to
No/Draft Mode to cause the rule to become invisible
to the rule resolution algorithm for all users (including
yourself), and to bypass validation of non-key fields. The
No/Draft Mode setting is useful in experimentation
and troubleshooting to assess the effect of two rule versions.
C-1119
|
Blocked
|
A circle within an X indicates that this rule has
Availability set to Blocked. Set
the value of this property to Blocked if you want
rule resolution processing to halt (with no rule found) when it
encounters this rule. The rule form colors change from greens to
grays. B-17118
This is a stronger form of No/Draft, because it
affects all lower-numbered versions of the rule, and versions
(in other RuleSets) that are below this version in the
user's RuleSet list. A blocked rule does not prevent rule
resolution from finding (and running) higher-numbered versions
in the same RuleSet, or finding rules with the same visible key
in a different RuleSet that is higher on the RuleSet list.

Final
|
An arrow and barrier in the key area indicates that this rule
has Availability set to Final. Set
this value of this property to Final if you want
this rule to be available (equivalent to Yes), but
want to prevent others from overriding this rule in any other
RuleSet.
A final rule can be superceded by a higher-numbered version
in the same RuleSet, but not by any version in any different
RuleSet.

|
Withdrawn
|
This image indicates that the rule has
Availability set to Withdrawn. A
withdrawn rule is never selected by rule resolution. In
addition, a withdrawn rule masks from rule resolution any other
rules which meet all of these tests: C-2555 5.2
- The other rule belongs to the same RuleSet
- The other rule belongs to the same major version of the
RuleSet, but a lower minor version or lower patch
version
- The other rule has the same Applies To
class (if relevant and other key parts match)
- If circumstance-qualified, is qualified with the same
circumstance type and value.

How availability works with circumstances and time-qualified
rules
A time-qualified rule or a rule containing a non-blank
Circumstance Property has its own
Availability value that may differ from the
Availability value in the base or underlying rule.
If a rule request meets the conditions of a time-qualified rule or
circumstance rule, the Availability of that rule
applies, not the Availability of the base rule. For
example, if the base rule has Availability set to
Blocked but a time-qualified rule (with the same key,
RuleSet, and version) has Availability set to
Yes, the time-qualified rule is visible and usable
throughout the time interval between its Start Time and
End Time values.
Class, library, RuleSet Name, and version rules are
always available. You cannot change the availability of instances of
these rule types.
