# Select rating plan factors in force

`RatingPlanFactorExtensions.AsOfDate` and `.RatingPlan` (`clsRatingPlanFactorCollection.vb:434-444`)

| Field | Value |
| --- | --- |
| **Operation ID** | OP-012 |
| **Trigger** | Validating or applying a rating plan modification factor |
| **Inputs** | A sequence of `clsRatingPlanFactor`, a date and/or a `Enums.RatingPlans` value |
| **Outputs** | Filtered sequence |
| **Primary components** | ``RatingPlanFactorExtensions.AsOfDate` and `.RatingPlan` (`clsRatingPlanFactorCollection.vb:434-444`)` |
| **Entry point** | `Business\SAIF.Business.Policy.Rating\clsRatingPlanFactorCollection.vb` |

## Steps

1. `AsOfDate` keeps factors where `EffectiveDate <= inAsOfDate` and
2. `RatingPlan` keeps factors whose `RatingPlan` equals the requested plan.
3. `clsARPCreditFactor.Factor` uses the resulting factor's `UpperLimit` when it `IsValid`, otherwise
4. Use the related data-access statements and tables for this operation: [SQL-038](../sql/SQL-038-saif-business-policy-rating.md), [SQL-039](../sql/SQL-039-saif-business-policy-rating.md), [SQL-040](../sql/SQL-040-saif-business-policy-rating.md), [RATING_PLAN_CODE](../database-tables.md#rating_plan_code), [RATING_PLAN_FACTOR](../database-tables.md#rating_plan_factor).

  S2 --> D1{Resulting factor IsValid?}
  D1 -->|Yes| S3[ARPCreditFactor uses the factor's UpperLimit]
  D1 -->|No| S4[Fall back per business rules]
  S3 --> Done([Filtered rating plan factor sequence])
  S4 --> Done
```

## Failure and edge-case behavior
- Review the linked business rules and SQL documents for the validation or data-access conditions that can block this operation.
