# Campaign Rule - Contributor Settings

## Requirement Definition
Configures funding contributors for a reward. If a reward is funded by entities other than the transacting merchant (or split between them), Contributors define the split percentage.

## Process Flow

### Pre-Conditions
- Rule must be created.
- Contributing merchants (Chains) must exist in OLS.

## Business Rules

### Data Schema

| Field Name | Description | Logic Type | Constraints / Rules |
|---|---|---|---|
| Contributor | The Chain funding the reward. | Enum (Lookup) | Required. Unique per rule. |
| Contributor Percentage | Percentage of cost to fund. | Decimal | Required. > 0. |
| Absorb Remainder | Absorbs rounding remainders. | Boolean | Required. Exactly one must be true. |

### Execution
- Total contribution must equal 100%.
- Transaction processing splits the awarded value across Contributors based on percentages.
- If no contributors are configured, the transacting Merchant (Chain) absorbs 100% of the cost.

## Exception Flow
- Validation failures block saving.
