错误1005：错误：150＆＃34;外键约束形成错误＆＃34;

Question

我正在尝试使用正向工程师从EER图创建数据库。我一直收到错误：

  

错误：错误1005：无法创建表appdev。order（错误号码：150）   ＆＃34;外键约束形成错误＆＃34;）

SQL代码：

 -- -----------------------------------------------------
        -- Table `appdev`.`Order`
        -- -----------------------------------------------------
        CREATE TABLE IF NOT EXISTS `appdev`.`Order` (
          `receiptno` INT NOT NULL,
          `pono` INT NOT NULL,
          `customer` VARCHAR(45) NULL,
          PRIMARY KEY (`receiptno`, `pono`),
          INDEX `fk_Order_Receipt1_idx` (`receiptno` ASC, `pono` ASC),
          CONSTRAINT `fk_Order_Receipt1`
            FOREIGN KEY (`receiptno` , `pono`)
            REFERENCES `appdev`.`Receipt` (`receiptno` , `pono`)
            ON DELETE NO ACTION
            ON UPDATE NO ACTION)
        ENGINE = InnoDB
