Rule resolution process and Rule availability

An availability of Available indicates the rule may be used during the rule resolution process.

You can view, copy, edit, and run rules in Dev Studio when the availability is set to Available.

An availability of Final indicates the rule may be used during the rule resolution process.

Rules marked as Final can be viewed and run in Dev Studio, but cannot be edited or copied into another ruleset with the same name. You cannot override a final rule except through a higher version in the same ruleset.

An availability of Not Available indicates the rule may not be used during the rule resolution process. When a rule set to Not Available is found during the rule resolution process, the rule in the next-highest version is considered for rule resolution. The following table represents an ordered list of rules. The availability of the rule named CreateRequest in the Purchasing:02-01-10 ruleset is set to Not Available. The rule in the next-highest version — Purchasing:02-01-05 — is considered for rule resolution.

You may choose to set the availability of a rule to Not Available during initial development. Doing so allows you to save a rule without validation. Rules marked as Not Available can be viewed, copied, or edited in Dev Studio, but do not run.

In the center of the following image, drag the vertical line to see the skipped rule candidate. The selected rule is in bold in the image on the right.

An availability of Blocked indicates the rule may be used during the rule resolution process. Rules marked as Blocked can be viewed, copied, or edited in Dev Studio, but do not run. If a blocked rule is selected during rule resolution, the run halts, and an error message is added to the log file.

In the following table, the availability of the highest version of the rule named CreateRequest in the Purchasing:02-01-10 ruleset is Blocked. This version of the rule is available during rule resolution but does not run. There are no higher versions of the rule available, so in the case of the example section rule, the section does not display.

Block a rule when access to the rule must not be used and you need more time to develop and release an updated rule.

In the center of the following image, drag the vertical line to see that the process does not skip any rule candidate. The selected rule is in bold in the image on the right.

An availability of Withdrawn indicates all rules that are in the current version ruleset and previous version ruleset and have the same purpose (or rule type) and Apply to: class are hidden and no longer considered after Availability is checked during the rule resolution process.

When a rule marked as Withdrawn is found during rule resolution, the system looks for an instance of the rule in the parent class or next highest ruleset in the application ruleset stack.

In the following table, the availability of the rule named CreateRequest in the Purchasing:02-01-10 ruleset is Withdrawn. All rules that are in the same ruleset with an equal or lower version number and have the same purpose and Apply To class are not considered during rule resolution. The rule named CreateRequest in the Purchasing:02-01-15 is considered during rule resolution because the ruleset version is higher than the ruleset version of the withdrawn rule. If the rule in Purchasing:02-01-15 did not exist, a rule in the parent class, TGB-Purchasing-Work, would be chosen.

Rules marked as Withdrawn can be viewed, copied, or edited in Dev Studio, but do not run.
