首先弄清楚ABAP Classic調(diào)試器和新調(diào)試器的區(qū)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(qū)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(qū)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(diào)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(diào)試器里查看A1這個類型為內(nèi)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.

一些小技巧：how to debug background RFC?

解決方案：使用事務(wù)碼sbgrfcmon

小技巧2：如何調(diào)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(wù)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

小技巧5：事務(wù)碼SRDEBUG

小技巧6：調(diào)試腳本
