# Recalculate modified premium on a specified rate tier

Renewal/what-if premium recalculation on a chosen rate tier

| Field | Value |
| --- | --- |
| **Operation ID** | OP-010 |
| **Trigger** | Renewal/what-if premium recalculation on a chosen rate tier |
| **Inputs** | Policy identity plus a rate tier (default "E") |
| **Outputs** | Scalar manual premium (out_manual_premium, ParameterDirection.ReturnValue) |
| **Primary components** | `clsPremiumSet.GetRecalcModifiedPremiumOnSpecifiedTier (clsPremiumSet.vb:649-730)` |
| **Entry point** | `Business\SAIF.Business.Policy.Premium\clsPremiumSet.vb` |

## Steps
1. Resolve the procedure name from the constant `Criteria.CALC_MANUAL_ON_SPECIFIED_TIER` = `pk72195_renewal.calc_manual_on_specified_tier` (`clsPremiumSet.vb:892`), appending `@POLDB` when the Policy database is selected.
2. Obtain a portal request via `DAL.GetPortalRequest(inDpi.PortalID)` (`clsPremiumSet.vb:709`).
3. Set `CommandType.StoredProcedure`, add inputs and the `out_manual_premium` return-value parameter.
4. Execute as a scalar request.
5. Return the recalculated manual premium to the caller.
