if (transaction == null) //if a transaction hasn't been passed, it isn't intended to has control over commit/rollback out of method, so app can do it
_transaction.Commit();
}
catch (Exception ex)

if (transaction == null)
_transaction.Rollback();
throw ex;
}
finally

DebugSpCommand(procedureName, parameters);
GetOutputParams(ref parameters, dbCmd);

_transaction.Connection.Close();
_transaction.Dispose();
}
}

Framework.ErrorHandling.ErrorHandler.HandleException(ex, "DATA_LAYER_POLICY");
Framework.Logging.Logger.Write(ex.Message, LogCategories.Debug);
iReturn = ex.Code;
}
