Error Message:

    public ObjectResult<global::System.String> P_GET_MST_CODE(global::System.String i_RES_TYPE, ObjectParameter v_RESULT)

        ObjectParameter i_RES_TYPEParameter;
        if (i_RES_TYPE != null)

            i_RES_TYPEParameter = new ObjectParameter("I_RES_TYPE", typeof(global::System.String));
        }
        
        return base.ExecuteFunction<global::System.String>("P_GET_MST_CODE", i_RES_TYPEParameter, v_RESULT);
    }

Below is the definition of the stored procedure.

    <Function Name="P_GET_MST_CODE" Aggregate="false" BuiltIn="false" NiladicFunction="false" IsComposable="false" ParameterTypeSemantics="AllowImplicitConversion" Schema="LEGACY">
      <Parameter Name="I_RES_TYPE" Type="varchar2" Mode="In" />
      <Parameter Name="V_RESULT" Type="varchar2" Mode="Out" />
    </Function>

Can anyone help me to solve this problem?
