我有一个使用注释映射的控制器; 客户端应用程序正在访问URL,并发送POST/GET数据.如何在此方法中访问请求对象？

我正在寻找一个语言结构或功能模块MOVE-CORRESPONDING IGNORING INITIALS.简单地说,我想要的东西完全相同MOVE-CORRESPONDING source TO dest但忽略了最初的所有字段source.

有那样的吗？

是否可以在ABAP中创建枚举(枚举),例如在Java中？

据我所知,我们可以定义一个具有固定值的域,但它们仅用于屏幕.

我正在创建一个简单的实体，并尝试将其持久化到Oracle数据库。这是我的特质：

import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.UniqueConstraint;

@Entity
@Table(name = "TBL_FLIGHT", uniqueConstraints = @UniqueConstraint(name = "flight_number", columnNames = {
        "comp_prefix", "flight_number" }))
public class Flight implements Serializable {
    @Id 
    private Long id;
    private String companyPrefix;
    private String number;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public void setCompanyPrefix(String companyPrefix) {
        this.companyPrefix = companyPrefix;
    }

    public void setNumber(String number) {
        this.number = number;
    }   

    @Column(name = …

我们在通过 netsuite API 更新付款时发现 Netsuite 失败，

我们看到的错误消息如下所示，Unable to find a matching line for sublist apply with key: [doc,line] and value: [123344,null]其中账单的123344位置是。external id有什么想法可能是什么原因造成的吗？

我发现了使用分层SALV（类CL_SALV_TREE）的一些非常奇怪的行为。

如果我set_data_row在创建节点实例之后直接使用该方法，那么我会收到正确的层次结构。

是否可以将用户定义的函数添加到实例中，CL_SALV_TREE而无需将 GUI 状态复制到使用此实例的报告中？

我想要做的是添加一个带有add_function方法的自定义函数。
