ORA-06550: строка 1, столбец 7: PLS-00306: неправильное количество или типы аргументов при вызове «INSERTBILL»

Привет, у меня проблема с вызовом процедуры хранения на сервере Oracle 10g.

Это моя таблица:

вот процедура хранения:

Это мой код С#, я использую массовую вставку SQL:

    public void InsertBills(List<CellPhoneBill> bills, int month)
    {
        var billsAsArrays = new BillDataAsArray(bills,month);

        using (var conn = new OracleConnection(GenerateConnectionString()))
        {

            var cmd = new OracleCommand
            {
                Connection = conn,
                CommandText = "INSERTBILL",
                CommandType = CommandType.StoredProcedure,
                ArrayBindCount = billsAsArrays.Ids.Count(),
            };

            try

                conn.Open();
                cmd.ExecuteNonQuery();
            }

            {
                throw ex;

            finally
            {

                conn.Close();
            }
        }
    }

Проблема в том, что если я тестирую процедуру в разработчике PL/SQL, все работает хорошо. Но если я попытаюсь вызвать эту процедуру из кода С#, я получу эту ошибку:

ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'INSERTBILL'
ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'INSERTBILL'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored

ИЗВИНИТЕ, Я ПУБЛИКУЮ СТАРЫЙ И НЕПРАВИЛЬНЫЙ КОД: "LmTime: paramater находится в коде C#. Но ошибка такая же. Я думаю, что что-то не так с типом параметров. В oracle все числовое, а в коде C# все десятичное, если значение это число. Как определить проблемную часть кода?

Спасибо за совет.
