# Determine the NCCI statistical class number

Statistical reporting requires the NCCI stat class for an adjustment

| Field | Value |
| --- | --- |
| **Operation ID** | OP-009 |
| **Trigger** | Statistical reporting requires the NCCI stat class for an adjustment |
| **Inputs** | Seven input parameters |
| **Outputs** | out_stat_class (4 chars, ParameterDirection.ReturnValue) |
| **Primary components** | `clsPremiumSummaryAdjustment.GetStatClassNumber (clsPremiumSummaryAdjustment.vb:549-580)` |
| **Entry point** | `Business\SAIF.Business.Policy.Premium\clsPremiumSummaryAdjustment.vb` |

## Steps
1. Build a `CommandType.StoredProcedure` command for `sp72151_determine_ncci_stat`.
2. Add the seven inputs and the return-value output parameter.
3. Execute through the data portal.
4. Return an empty string when the output is `DBNull` ([BR-022](../business-rules.md#br-022-null-statistical-class-becomes-an-empty-string)).
