abap - 附加排序表时的 ABAP 短转储

Question

当我将一行附加到排序表时，为什么我的 ABAP 程序会短转储？

ST22 节目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排序表时程序短转储

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"

注意如果您有一个UNIQUE密钥，您仍然会得到一个简短的转储，因为您使用了两次相同的密钥
