# Determine policy minimum premium

Calls the Oracle stored procedure `pk73069_rating_procs.get_minimum_expense_constant` to compute the minimum premium amount for a premium-history set, with any execution failure silently swallowed.

| Field | Value |
| --- | --- |
| **Operation ID** | OP-POL-007 |
| **Trigger** | Caller reads `PolicyInformation.PolicyMinimumPremium(inDPI, inPremHistSetID)` |
| **Inputs** | Data portal info, premium-history set ID |
| **Outputs** | Decimal (0 on failure or no result) |
| **Primary components** | `PolicyInformation.PolicyMinimumPremium` |
| **Entry point** | `SAIF.Business.Policy\PolicyInformation.vb` |

## Steps

1. Caller reads `PolicyInformation.PolicyMinimumPremium(inDPI, inPremHistSetID)`.
2. A stored-procedure call is issued: `pk73069_rating_procs.get_minimum_expense_constant` ([SQL-010](../sql/SQL-010-policy-minimum-premium-procedure.md)), `CommandType = StoredProcedure`, input `in_prem_hist_set_id`, outputs `out_minimum_premium_amount` and `out_expense_constant_amount`.
   - Origin note: the procedure body resides in the Oracle database ([pk73069_rating_procs](../procedures/pk73069-rating-procs.md), status `not-found` — retrieval not performed this run).**
3. Execution is wrapped in `Try...Catch` with an **empty Catch block** — any provider/database exception is silently swallowed.**
   - On failure: no error is surfaced to the caller; execution falls through to step 4.
4. If `Result` is not `Nothing`, the output parameter `out_minimum_premium_amount` is read as the return value; otherwise `0` is returned.

	D2 -->|No| EndVal([Return out_minimum_premium_amount])
```

## Failure and edge-case behavior
- The empty `Catch` block silently swallows any stored-procedure execution failure; whether this is intentional "default to zero" behavior or an unhandled-error gap could not be confirmed from source alone.**
- `out_expense_constant_amount` is read into a local variable but never consumed by the caller — only `MinPremium` is returned.*
