developer_list = VALUE #( ( name = 'AAA' focus_language = 'ZH' salary = 1 )

"方法一:使用Loop循环手动赋值
LOOP AT developer_list ASSIGNING FIELD-SYMBOL(<temp1>).
APPEND INITIAL LINE TO presale_list1 ASSIGNING FIELD-SYMBOL(<temp2>).
<temp2>-name = <temp1>-name.
<temp2>-focus_area = <temp1>-focus_language.

ENDLOOP.

推荐方法三，动态的话就用方法二。
