咱们晓得 ABAP 零碎里有一个有用的工具,事物码 SE10,输出用户名称,能够查看该用户在本零碎上创立的传输申请 (Transport Request) 列表:

点击 Display 按钮,能看到用户名 WANGJER 上面的所有传输申请:

每个传输申请能够开展,查看外面具体蕴含的 ABAP 对象。很多 ABAP 对象,比方上图蓝色高亮的 ABAP 类办法,双击之后,能够用 ABAP 编辑器关上这些办法,查看其实现源代码。

本教程咱们曾经用了几个步骤的篇幅,介绍了 ABAP ALV 的开发步骤:

  • 44. 27 行代码开发一个最简略的 SAP ALV 报表
  • 45. 48 行代码给 ABAP ALV 报表的数据行削减色彩成果
  • 46. 77 行代码实现 ABAP ALV 中的双击事件处理
  • 47. SAP ABAP ALV 档次程序表如何应用双表头 (Multiple Headers) 进行数据输入
  • 48. 如何在 SAP ABAP ALV 报表里以交通灯的形式显示某一列的值
  • 49. 在弹出对话框窗口里显示 SAP ABAP ALV 列表

本文咱们来应用以前所学习的常识,入手开发一个相似 SE10 的工具。这个工具也是笔者理论工作中开发的一个工具,这里分享给各位 ABAP 学习者。

这个工具容许用户输出指定的用户名,执行之后,在 ALV 列表里列出该用户在该零碎创立的所有传输申请,并主动把传输申请里蕴含的 ABAP 对象 (包含 ABAP 类,ABAP DDIC 对象等等) 也显示进去,如下图所示:

单击上图的 ALV 行我的项目,同样能主动跳转到 ABAP 编辑器里,关上这些 ABAP 对象,成果如下图所示:

上面咱们介绍这个工具的具体设计思路,开发步骤和全副源代码。

这个工具的骨干程序很精简,代码如下,蕴含 4 个 ABAP include 程序。每个 ABAP include 程序负责实现一项特定的业务逻辑。通过将业务逻辑拆分到不同的 ABAP include 程序,使咱们工具实现的代码构造和逻辑更清晰,可读性更好。

骨干程序和 4 个 ABAP include 程序的 smc,代表 Social Media Cockpit,这是笔者过后参加的 CRM 我的项目的缩写。

zsmc_data

咱们在 SE38 里创立的 ABAP 程序,默认类型都是能够运行的报表,即 executable program,如果要创立 include program,从下拉列表里抉择对应的类型即可。

这个 include 的工作是定义所有须要在这个工具里应用到的 ABAP 变量:

ZSMC_TR

这个 include 的工作是从数据库表 e070 里读取出指定用户在以后 ABAP 零碎里创立的所有传输申请的 id,存储到 ABAP 内表 lt_trlist 里。

比方在笔者应用的 AG3 零碎上,我总共创立了 595 个传输申请:

e070 数据库表只保护了用户名和传输申请 id 之间的关系,如果咱们想晓得每个传输申请里蕴含了哪些 ABAP 开发对象,须要采取其余方法来查找。

ZSMC_PREPARE_DATA

这个 ABAP include 负责将 ZSMC_TR include 里编写的逻辑,即从 e070 数据库表里取出的 ABAP 传输申请 id 进行解析,取出每一个传输申请蕴含的 ABAP 对象。

解析操作通过 Function Module 实现,解析后果如下图所示:

上图函数的 Tables 参数 et_e071,存储的就是传输申请里蕴含的不同类型的 ABAP 对象。这些 ABAP 对象的类型,通过字段 PGMIDOBJECT 进行辨别。

  • R3TR.CLAS, 代表存储在传输申请里的是 ABAP 类名称
  • LIMU.METH, 代表存储在传输申请里的是 ABAP 类的办法实现

ZSMC_ALV

负责 ABAP ALV 的数据显示和点击事件处理。

如图所示,咱们应用 Function Module REUSE_ALV_GRID_DISPLAY 来输入 ALV 报表。

这个函数有一个输出参数 i_callback_user_command, 能够指定一个用户自定义的 subroutine,用于解决 ALV 的点击事件。

如下图所示,当咱们单击 ALV 报表某些能够点击的列时,咱们通过代码 123 行指定的 subroutine,ALV_USER_COMMAND 会主动被触发,在这个 subroutine 里咱们调用本人编写的另一个 subroutine display_object,来实现主动关上对应的 ABAP 编辑器以查看的性能。

比方咱们单击下图红色的行我的项目 CL_ABAP_GIT_ISSUE_IMAGE_TOOL

从调试器里的函数上下文调用栈能看出,咱们编写的 subroutine ALV_USER_COMMAND 被调用,输出参数 ct_selfield 蕴含了被点击的行我的项目的索引 12,所以咱们能够从 ALV 报表的数据源,lt_dev_object 内表里,通过 READ TABLE INDEX XXX 的 ABAP 语句将该行我的项目的明细读取进去:

行我的项目 ABAP 对象的类型,通过输出参数 ct_selfield 的字段 fieldname 来辨别。如果字段名称为 TRKORR, 阐明这个行我的项目是一个传输申请,此时调用第 150 行的工具函数 TR_PRESENT_REQUEST 来显示这个传输申请。

否则,阐明该行我的项目是一个一般的 ABAP 对象,此时调用能解决绝大多数 ABAP 对象显示性能的 RS_TOOL_ACCESS 来实现 ABAP 对象的显示操作。

ALV 报表里具体哪些列反对单击事件处理呢?只须要将传入函数 REUSE_ALV_GRID_DISPLAY 的输出参数 it_fieldcat 里蕴含的每一列对应的 hotspot 字段设置为 X 即可。

如下图所示,代码的语义就是,咱们冀望 OBJ_NAMETRKORR 这两列,即对象名称和传输申请号可能反对单击操作。

这两个反对单击操作的列如下图所示,用户很容易辨别,因为其值下有一条下划线,显示成超链接的成果。
