今天使用APPEND LINES OF?table1 TO table2的時候，發(fā)生了如下Dump:

ITAB_ILLEGAL_SORT_ORDER_BLK

Error analysis
????You want to insert several lines at once into the sorted internal table.To do this, you use:

INSERT/APPEND LINES OF SrcTab ... INTO/TO DstTab ...

However, when the line 1 of the source table SrcTab was inserted, the
sorting sequence - determined for the target table DstTab via

its key - was destroyed.

仔細查看發(fā)現(xiàn)table2 是sorted table,如果table1的key值不是按順序排列的話，或者table2不為空，你插入的時候導致順序錯誤。都會發(fā)生dump.

解決的辦法： 使用?INSERT LINES OF table1 INTO TABLE table2.

?

同樣的道理，單條插入的時候，可以使用

INSERT line INTO TABLE sorted_table.

來代替

APPEND?line?TO sorted_table。

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"

Use INSERT in stead:

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"

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