附加排序表时的 ABAP Short Dump [英] ABAP Short Dump on append of a sorted table

问题描述

为什么我的 ABAP 程序在我向已排序的表中附加一行时会短转储?

Why does my ABAP program short dump when I append a line to a sorted table?

ST22 显示 ITAB_ILLEGAL_SORT_ORDER

data: sorted_tab type sorted table of ty_tab with non-unique key key,
      line       type ty_tab.

line-key = 1. 
append line to sorted_tab.  "works fine" 

line-key = 2. 
append line to sorted_tab.  "works fine" 

line-key = 1. 
append line to sorted_tab.  "<==== Short dump here" 

推荐答案

当以错误的排序顺序附加已排序的表时，程序会出现短转储

The program short dumps when appending a sorted table in the wrong sort order

data: sorted_tab type sorted table of ty_tab with non-unique key key,
      line       type ty_tab.

line-key = 1.
append line to sorted_tab.  "works fine"

line-key = 2.
append line to sorted_tab.  "works fine"

line-key = 1.
append line to sorted_tab.  "<==== Short dump here"

改用插入:

data: sorted_tab type sorted table of ty_tab with non-unique key key,
      line       type ty_tab.

line-key = 1.
insert line into table sorted_tab.  "works fine"

line-key = 2.
insert line into table sorted_tab.  "works fine"    

line-key = 1.
insert line into table sorted_tab.  "works fine"

注意如果你有一个UNIQUE键，你仍然会得到一个简短的转储，因为你两次使用同一个键

Note If you had a UNIQUE key you would still get a short dump because you're using the same key twice
