這篇文章主要講解了“SAP 的 ABAP 調試器怎么使用”，文中的講解內容簡單清晰，易于學習與理解，下面請大家跟著丸趣 TV 小編的思路慢慢深入，一起來研究和學習“SAP 的 ABAP 調試器怎么使用”吧！

首先弄清楚 ABAP Classic 調試器和新調試器的區別：

Classic debugger:

(1) Static breakpoint

a. BREAK-POINT : non-user specific
b. BREAK user name user specific

(2) Dynamic breakpoint

New debugger:

(1）Static breakpoint
(2）Dynamic breakpoint
a. session breakpoint
b. external breakpoint

Session 斷點和 External 斷點的區別

(1) Session BP is only visible in all external sessions belonging to the same user session, while External BP is visible across all user sessions. Therefore, only External BP is valid for BSP / Webdynpro debugging.

(2) When a user logs off, Session BP will be deleted while external BP persists.

By setting this flag, if external session A is running, and in external session B (A and B belongs to the same user session) you set a session breakpoint in the program source code, the BP will be triggered immediately .

ABAP 獨占斷點 (Exclusive Breakpoint) 和非獨占斷點的區別

下圖是非獨占斷點：

下圖是獨占斷點：

Exclusive mode means the application to be analyzed exclusively occupies a work process of the application server during debugging. If all exclusive debug work processes are occupied, the Debugger is switched to non-exclusive mode. (rdisp/wpdbug_max_no)

Limitation for non-exclusive mode:

Due to technical limitations in ABAP debugger implementation, there are following limitations when debugger is run under non-exclusive mode:
(1) No possible to debug statement between SELECT and ENDSELECT. In this case, program terminates with this error:

(2) No possible for conversion / field exit.
(3) No possible for debugging in production system, program terminates with exception DEBUGGING_NOT_POSSIBLE.

ABAP 調試器里的一些指標該如何閱讀？

考慮下面這段最簡單的 ABAP 代碼：

調試器里查看 A1 這個類型為內表的變量：這里的 [2×1(8)] 是什么意思？

2: table row number
1: table column number
8: byte length of table row

The time for which the new Debugger is active is determined by the profile parameter rdisp/max_debug_lazy_time – which is set to 600 seconds in the standard version. After this time space has elapsed, the Debugger process is exited automatically and control is passed back to the application.

解決方案：使用事務碼 sbgrfcmon

小技巧 2：如何調試 update task

小技巧 3：如何使用 ABAP 觀察點 Watch point

練習：我們進入事務碼 SE09 時，會觀察到 User 字段會自動被填充成當前登錄用戶。如何通過觀察點快速找到是哪一行代碼賦的值？

When we use SE09, how can we find the logic of the User? When and where is this field filled? What does content come from?
Debugging step by step will be very time-consuming.

小技巧 4：使用 ABAP 檢查組 Check group
