Selection of a Winning Rule
The classification and crediting processes use this method to determine the winning rule:
-
Calculate Scores
Assign each rule a score, calculated using these attributes of the rule:
-
Rule rank, provided by the user: Rules with a lower rank get a higher score.
-
Position of the rule in the hierarchy: Rules lower in the hierarchy (for example, a leaf) get a higher score.
-
Rank of the parent rule: A rule with a lower rank for the parent rule gets a higher score.
-
-
Select qualified rules
Evaluate the deployed rules against the transaction attributes to determine the qualified rules that match.
-
Select winning rules
Select the winning rules from the qualified rules based on the calculated score. The rule with the highest score wins.
If there's a contention, meaning there are more winning rules with the same absolute score than the number of winners, then the application selects the winning rules randomly. However, if the hierarchy isn't modified (stays consistent), then the same winning rule is selected every time the process runs.
Example: Multiple Matching Rules with One Winner
Here's an example credit rule hierarchy:
|
Node Level |
Rule Name |
Rank |
Criteria |
|---|---|---|---|
|
Root Node: Level 0 |
Root Note |
None |
None |
|
Branch 1: Level 1 |
Rule 1 |
2 |
Transaction Type = Manual |
|
Branch 1: Level 2 |
Rule 1.1 |
4 |
Country = US |
|
Branch 2: Level 1 |
Rule 2 |
3 |
Sales Channel = Direct |
|
Branch 2: Level 2 |
Rule 2.1 |
1 |
Country = US |
This table shows the selection process and the calculated score:
|
Node Level |
Rule Name |
Rank |
Criteria |
Score |
|---|---|---|---|---|
|
Root Node: Level 0 |
Root Note |
None |
None |
10 The rank for the root node is 99999999 to calculate the score, because the rule rank isn't provided. |

Branch 1: Level 1 |
Rule 1 |
2 |
Transaction Type = Manual |
515 |
|
Branch 1: Level 2 |
Rule 1.1 |
4 |
Country = US |
600 |
|
Branch 2: Level 1 |
Rule 2 |
3 |
Sales Channel = Direct |
315 |
|
Branch 2: Level 2 |
Rule 2.1 |
1 |
Country = US |
400 |
Winning Rule: All four rules are qualified. Since the calculated rank for Rule 1.1 is the highest, it becomes the winning rule and the transaction is assigned to credit receivers from that rule.
