附加排序表时的 ABAP 短转储

Question

为什么我的 ABAP 程序在我将一行附加到排序表时会短转储？

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" 

Answer 1

以错误的排序顺序附加已排序的表时，程序会进行短转储

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"

使用 INSERT 代替：

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，因为你使用了两次相同的键
